Monument To Lost Lights
From Destinypedia, the Destiny wiki
The Monument to Lost Lights is a vendor located between the two vault kiosks in the Tower. At the Monument, players can purchase Exotic Weapons that are now unobtainable through their original means. Players can also acquire Pinnacle Weapons from past seasons.
The cost to purchase weapons from the Monument to Lost Lights ranges, but all Exotics require an Exotic Cipher, which can be acquired through Xûr, Agent of the Nine. All exotic weapons cost Ascendant Shards and Glimmer and most also require World Materials such as Baryon Bough. Some Exotics, however, originated from Raids and thus require Spoils of Conquest instead of World Materials.
