My Nightstalker hunter is an Exo by the name of Giellman-10 who works closely with the Reef and the House of Judgement. Giellman-10 was originally a human by the name of Gilbert whose family worked closely with Clovis Bray and was the son of Doctor Finn Giellman, the lead developer of Project Deep Stone for the Exoscience program. When he was a young adult, Gilbert would hear more and more of a nanotechnology codenamed SIVA, so he would sneak into the facility and attempt to wield it. But he lost control of it and it would take control of him; the alarms would be set off, alerting many of the staff including Finn Giellman. After containing the SIVA, Gilbert's vitals were left severely damaged and were beginning to fail. So, Doctor Finn decided to have him turned into an Exo via Project Deep Stone to keep alive. Gilbert's new life would not have long in the world as he awoke to see dark ships coating the sky, the buildings crumbling and the ice under his feet cracking. He fell through a chasm in the ice and his lights went out again as Project Deep Stone was consumed the cold and the Dark. Gilbert would be resurrected by a Ghost, whom he would name Ana, several years later in a cave entombed in ice. After walking through tunnels that seemed to go on forever, Gilbert finally reached the exit step out into a cold storm to see abandoned buildings and a tall metal structure. Gilbert decided to take shelter in one of the buildings until the storm subsided. There he would find the name Giellman on the remnants of papers. This must have triggered something he would begin to have flashbacks of his former life, resulting in his first wipe. Curious of how this one word did this to him and curious to discover why it made have those visions, Gilbert would take the name Giellman. After finding a Jumpship, Giellman and Ana would begin their long journey back to the city. As they passed through the Reef, they were shot down by Awoken patrolers and crashed onto a nearby asteroid. After being revived, Giellman was brought to The Queen who would allow him and Ana to live by serving her, and they would agree. For the next several years and several wipes of his life, Giellman would work alongside Uldren Sov, Petra Venj, and the rest of the Awoken forces during the Reef Wars against The House of Wolves, with the significant battles he was in including The Scatter where he first witnessed the power of The Harbingers and the Siege of Pallas, in addition to numerous scouting missions. After the Awoken won the wars and Mara Sov became the new Kell of the House of Wolves, Giellman would master hand-to-hand combat and improved aiming from some of best Captains of the Wolves and would learn the Eliksni language; in addition to the House of Wolves under Mara Sov's command, Giellman would get valuable combat experience from the Fallen, Hive, Vex and Cabal locked within the Prison of Elders.
