The Sleeper Stirs

The Sleeper Stirs is a quest that rewards the exotic heavy Fusion Rifle Sleeper Simulant.

Unlocking
The quest is unlocked by collecting 4 fusion rifle artifacts, all of which are named "DVALIN-RAS8711", and turning them in to Banshee-44. The artifacts drop randomly from enemies throughout the game. Once this is done, at some point in the future a mission named The First Firewall will become available.
