Ada-1

Ada-1, born as Adelaide Meyrin, is an Exo gunsmith and the head of the Black Armory.

The Collapse
Ada-1 was born as Adelaide Meyrin during the Golden Age and was the daughter of Henriette Meyrin, one of the three founding leaders of the Black Armory. During the Collapse, she was fatally injured by a minion of the Darkness, forcing her mother to save her life by implanting her consciousness into an experimental Exo frame, becoming Ada-1.

On the Run
Proto-Warlords killed her mother and the co-leaders of the Black Armory, and she survived through the ages.

Reclaiming the Past
Ada eventually reached The Last City and set up a hidden Black Armory refuge within the walls of the growing city under the Traveler. She offered her wares to those who needed to defend themselves, but refused to work with the Vanguard and its Guardians due to her past with rogue Lightbearers. However, the Red War disrupted the operations of the Black Armory, and the Volundr Forge fell into the hands of the Red Legion in the European Dead Zone. Without the forge, Ada could no longer produce weapons for the Black Armory's customers and allies.

As Ada pondered what to do, she was surprised when the Guardian known as the Young Wolf entered the Black Armory. As they approached a display containing a model of Izanagi's Burden, Ada approached them and stated that weapon was special, as it had born witness to and helped avenge the death of the Black Armory's founder at the hands of Lightbearers. She angrily declared that they were not welcome in the Black Armory's halls, but the Guardian presented a token given to them by The Spider, one of Ada's allies who had grown tired of the Black Armory being shut down. Reluctantly, Ada allowed the Young Wolf continued access to the armory and to enlist their help in reclaiming the Volundr Forge.

A Place in the Tower
When the Festival of the Lost was held later that year, Ada participated in it and decorated the Black Armory in Festival decorations. When the Young Wolf visited her, Ada explained the Festival was new to her but that the Black Armory had a rich tradition of celebrating history and memory. She thanked them for welcoming her into the Tower's community and letting her join the City's festivities.

When the Pyramids arrived within the Solar System, Ada volunteered her equipment and expertise to work on Project Stronghold alongside the Future War Cult to prepare the Last City for a possible attack from their ancient enemy.

Personality and Traits
At first glance, Ada-1 is secretive, distrusting and contemptuous, mostly towards the Guardians due to the hardship she had faced years prior at the hands of a rogue Risen. This has left her rather unwilling to associate herself and her Armory with the Guardian in any way, regardless of their reputation as heroes to the Last City and the countless foes they have defeated that have threatened the Solar System. Despite this, Ada does possess enough manners that should a Guardian possess a pass to access her Armory then she will welcome them but remains very distrusting. In addition, she feels that the Last City needs more protectors besides the Guardians.

Ada-1 takes great pride in her order, the Black Armory, finding that her wares surpass all others, and no one should even try to counterfeit Black Armory weapons. As a result, she is very confident that those who buy her wares will be more than satisfied and likewise becomes furious should her order's wares be pilfered or stolen.

In the wake of the Kell's Scourge's rise to power, their theft of Black Armory weaponry, Ada ultimately put aside her ill-feelings towards the Guardians for the greater good, knowing full well what kind of damage the terrorist Fallen could bring with her order's wares. In addition, she grows grateful of the Guardians efforts to restore the Black Armory's old forges. In time, and in great effort on the Guardian's part, Ada's attitude towards the Guardians begins to soften, especially as they aid her in recovering the lost papers and secrets of the Black Armory's founders. She stated that she was honored to have the Guardian bear the weapon Izanagi's Burden and putting an end to Siviks, Lost to None. She became especially grateful towards the Guardian for recovering the Obsidian Drive, a lost piece of herself which enabled her weapon-upgrading abilities.

Despite being the vendor to the Black Armory, it has been said that Ada often prefers solitude to interacting with others, suggesting that she is an introvert.

Trivia

 * Prior to Black Armory's reveal, many thought her to be the Exo Gunsmith, Gaunt, as a result of fake Black Armory leaks.
 * The original concept of her being an Exo was to be a walking Black Armory Forge, through the Obsidian Accelerator.
 * She is part of the French family, the House of Meyrin.
 * Among the Exos encountered in the series, Ada-1 is the only one without a visible moving mouth, possessing LEDs which activate when she speaks instead. However, an excerpt from Destiny: The Official Cookbook implies she is capable of eating and drinking, though it does not depict her doing so or explicitly identify her.
 * If one lingers around Ada-1 long enough, she can be heard singing "Le Temps Des Cerises.", a French song composed by Jean-Baptiste Clément in 1866. She learned the piece from her mother.
 * There is currently a bug in the game, where Ada's feet sink into the ground. This makes her look very short
