Prison of Elders

"Prove your Light."

- Grimoire description

The Prison of Elders is a prison facility in The Reef, under the oversight of Variks, the Loyal. It is based on the House of Judgment's traditions for settling disputes between Fallen through trial by combat. The Archon Priest Aksor was previously a prisoner before later being retrieved by Taniks and having his soul restored by the House of Winter on Venus. The Prison of Elders is also known to contain members of the House of Wolves that were captured during the Reef Wars, though it also contains Hive, Vex and Cabal inmates who have attacked the Reef. These prisoners are considered "trophies" by the Reef, kept cryogenically frozen for the Queen's benefit. Though since Skolas' rebellion, the Queen now wants the prison cleared out, and has recruited the Guardians to do it.

A year after the Red War, the undead Fallen horde known as the Scorn orchestrated an incredibly massive breakout from the prison, following a lack of order after Mara Sov's and Variks' disappearances. Uldren Sov was behind the escape, and executed Cayde-6 with his own weapon after he attempted to stop the breakout alongside the Guardian. Numerous prisoners not strictly affiliated with the Scorn, collectively referred to as the Wanted, also escaped the prison, going on to roam Patrol zones and roost in Lost Sectors. The Prison of Elders is also the location of the Strike Warden of Nothing.

Gameplay
The Prison is featured in the House of Wolves as part of the new Arena game mode. It is limited to 3 players. Four missions are available each week at different Levels. The Level 28 mission includes matchmaking and is always random. The other three "challenge" missions are at Levels 32, 34, and 35, and require pre-made fireteams. The Level 32 and 34 missions rotate weekly; the Level 34 mission will be replaced with something new, while the Level 32 mission will feature the previous week's Level 34 mission. The Level 35 mission is always Skolas's Revenge.

A single session consists of 5 rounds of 3 waves each, except for Skolas's Revenge which features 6 rounds. The final round of a session is a boss battle. Players spawn in the Airlock, a small central room that connects to the Prison's four chambers, each home to one of the four enemy races. As introduced in Forsaken, each one connected to a different prison block that housed each different race. A-Block holds Fallen, B-Block holds Vex, C-Block holds Cabal, and D-Block holds Hive. Once a round begins, a modifier is activated and players are directed to one of the chambers. After completing a round, players must return to the Airlock to begin the next round.

After completing the boss round of a Prison of Elders challenge mission, a gate in the Airlock's floor opens and allows players to descend into a treasure room. The room contains three chests that can only be opened once per session: two small chests that may drop rare items, and one large chest that requires a Treasure Key to open and may drop Reef-themed gear as well as exotic items. Other items that can drop from the chests include Strange Coins and Motes of Light. Players with multiple Treasure Keys may repeat a Prison of Elders session to refresh the large chest so that the Keys can be used; the large chest can be opened multiple times per week, the only limit is the number of Treasure Keys in the player's possession. As of the April Update, Prison of Elders now has two extra game modes: Level 41, which has a chance of hosting Taken and Level 42, which is known as Challenge of the Elders.

As the Prison of Elders is a highly variable environment, see Prison of Elders/Strategy for more details.

Missions

 * Broken Legion—"Valus Trau'ug seeks to prove his might by crushing all who challenge him."
 * Cult of the Worm—"Gulrot, Unclean has been summoned by the Worm Keepers. Don't let the beast's filth spread beyond the prison."
 * Machine Wrath—"Archon Servants have raised their own corrupted Servitor-god, Kaliks Reborn. Defeat it and be rewarded."
 * Skolas's Revenge (Level 35 only)—"Skolas and his crew challenge the Guardians who captured him. Face him with a Fireteam of three. End him."
 * The Forever Eater—"Qodron, a Vex chronovore, sees only one outcome: your demise. Prove it wrong."
 * Urrox's Grudge—"The Flame Prince Urrox vows to burn the Light until all that remains is Darkness and bone."
 * Last Call (Forsaken owners only) "Fight alongside Cayde-6 to help Petra Venj regain control of the dangerous Prison of Elders."

Round Modifiers
Each round features a specific modifier that can force Guardians to adapt their strategy. The modifier is active for the entirety of the round. Skolas's Revenge features two modifiers per round. In addition to existing modifiers, House of Wolves introduces eight new ones:


 * Airborne—players deal more damage in the air.
 * Brawler—player melee attacks are more powerful
 * Catapult—grenades recharge at an increased rate
 * Exposure—player shields are increased, but don't replenish
 * Grounded—players take more damage while in the air.
 * Lightswitch—minions of the Darkness deal far more melee damage.
 * Small Arms—primary weapons are more powerful
 * Specialist—special weapons are more powerful
 * Trickle—abilities recharge at a reduced rate

Critical Objectives
During some waves, Variks will issue a time-sensitive Critical Objective that Guardians must complete during the battle. Failing to complete a Critical Objective will cause Variks to invoke Warden's Punishment, a debuff that immediately kills the Guardians and forces them to restart the round.


 * Destroy Splinter Mines—mines will appear around the arena. Destroy them within thirty seconds.
 * Defusing Splinter Mines—capture zones that appear one at a time across the arena. Once a zone appears, players have thirty seconds to capture it.
 * Eliminate Target—kill a powerful enemy before he escapes the arena.

Gifts from Variks
Occasionally, at the start of a wave Variks will send Guardians a helpful item.


 * Scorch Cannon—a pickup weapon that can fire explosive shells with a timer.
 * Heavy Ammo crate—a single-use ammo crate like those found in the Crucible.

Generic
Generic bosses are fought on Round 5 of the Level 28 Prison of Elders. They may also appear as a boss during Rounds 1-4 on one of the challenge modes. Generic bosses lack any special abilities that challenge mode bosses have. However, as of the April Update, these bosses will gain special abilities when encountered in the most difficult mode of Prison of Elders yet: Challenge of the Elders.
 * Overmind Minotaur
 * Pilot Servitor
 * Val Aru'un
 * Wretched Knight

Challenge
Challenge mode bosses are much more difficult to fight, as they all come with their own special abilities.
 * Gulrot, Unclean—can spew bile that dramatically slows down Guardians for ten seconds.
 * Kaliks Reborn—can gorge on Ether from Archon Servants to regenerate its own health.
 * Skolas, Kell of Kells—is armed with a Scorch Cannon. He is initially protected by servitor bonds, reducing all incoming damage by a significant amount. After these bonds are broken, he will taint a Guardian's Light and inflict them with a debuff called "Devouring Essence" that must be shared with other players, or they will die.
 * Qodron, Gate Lord—can capture Guardians in detainment bubbles, and will kill them via Suppression Field. These bubbles can be destroyed with non-explosive attacks.
 * Urrox, Flame Prince—can inflict the "Searing Flames" debuff, where the entire floor is on fire for ten seconds. Jumping repeatedly will greatly reduce damage.
 * Valus Trau'ug—can change his own elemental shield to a different color every time it is destroyed.

Mission Rewards
These rewards are guaranteed for completing a Prison of Elders session and challenge missions. The challenge mission (Level 32, 34, and 35) rewards can only be acquired once per week.

Crystal Barrows
In addition to the above mission rewards, players can enter the treasure room in the Crystal Barrows. They can open the two smaller chests, which rewards lesser items such as strange coins and motes of light, but the big chest can only be opened with a treasure key, which can be used even on the Level 28 version. The chest can drop legendary Queen-themed equipment, legendary Fallen-themed equipment, and (once per character) a Level 36 Exotic weapon.

Prison Layout
The Prison of Elders is a massive complex in total, with at least four main prison blocks and a minimum of fifty-four floors. A-Block and B-Block are known to house Fallen denoted as Scar and Rats respectively, C-Block contains a significant number of Cabal, and D-Block contains Hive. It is unknown what blocks the Taken and Vex are placed in, as they have not been shown to be associated with any particular one, though it is known that the Prison keeps a significant quantity of them. It could be that these blocks are organised in accordance to the security required to contain certain inmates, which would explain why the Fallen remnants of the House of Scar are placed in a different block from their unaffiliated rat counterparts.

The Combat Arena where the gamemode from Destiny 1 takes place is located in the upper levels of the prison, directly above the Queen's treasure room and the Warden's command center farther below. Seeing as it has access to enemies from every block, this is likely located near the center of the complex. A large section of the Prison is built in a large cylindrical spire, with prisoners held on the exterior walls and control stations suspended in the middle, connected by large catwalks. It is possible that there are actually two or more of these cylindrical areas, as the area shown in Last Call and the climax of the Warden of Nothing strike both take place in structures of similar design, though with different construction. The former has no roof and is open to the sky, and contained the Prison's security hub before Cayde-6 dislodged and destroyed it, while the latter has a closed roof and contains the Warden's command center. It is also possible that these two areas are actually stacked on top of each other, in which case the Prison would possess over a hundred decks. Alternatively, as shown in the aforementioned strike, guardians travel through a vacuum tube from one section of the prison, past a cylindrical area, and into the Fallen side of the combat arena, implying that the Prison could be laid out in clusters of these cylindrical chambers, perhaps being the Blocks themselves.

The Prison holds its criminals in one of two different ways: traditional barred cells and cryogenic pods. Standard enemies seem to be relegated to the simpler cells while the more dangerous members are frozen and stored below. Some or all of these cryo-pods are fitted with propulsion mechanisms similar to an escape pod, though the means for this is unknown. It could be that this is a more effective way to transport these high-level targets across long distances without risking the safety of a traditional crew, such as how Skolas was sent to The Nine. Many of these pods rained down on the Tangled Shore during the Hunt for the Scorn. Other pods were sent farther and contributed to the foes scattered across the system that The Spider placed Wanted bounties on. For transportation withing the Prison, elevators, vacuum tubes, and train-like prison transports are the main means of getting from place to place. The transports are automated and have room for six prisoners in cryo-pods, three on either side. When the Warden took control of the prison, these transports ran amok, smashing at high speed into anyone foolish enough to get in the way of their tracks. It is likely these transports are only for high-level threats due to their small passenger size, as the vacuum tubes like those used to transport detainees up to the Combat Arena have a much higher capacity. Elevators are present for use by Prison staff and feature four crash seats spaced apart at medium intervals, as the immense height of the Prison would be deadly if the elevator were to fail. The main airlocks to the outside are located on Deck Zero, though there are also access points in lower decks used to covertly transport prisoners. Uldren Sov was delivered through one of these.

In case of a Prison riot, turrets were installed in the catwalks that could be controlled remotely from the Security Hub.
