Your Guardian: What colour will his/her armour/cloak be, what kind of personality will he/she have, what class and race will he/she be, what kind of play style will they have.. etc (detailed answers appreciated, not necessary though)
EDIT: Now that I know Exo are robots, not human in exoskeletons, I've made a few changes...
[b]Name:[/b] Kappa
[b]Species:[/b] Exo
[b]Age:[/b] ?
[b]Height:[/b] 6'6
[b]Class:[/b] Warlock
[b]Description:[/b] He's gentle soul at heart, if a bit cynical and prone to dry humor. He generally prefers study to battle and likes to do both on his own more often than not. He is quite bright though, and well understands the value of a squad when the situation may be more than he can handle. Not that he'll call for help quickly though, he's too stubborn for his own good. As for his appearance, he's an Exo. He looks like a tall dark skeleton-like robot with glowing red-orange eyes. Suffice to say, children run in fear of him.
[b]Background:[/b] When Kappa awoke, he was like every other Exo, devoid of memory and purpose. This, however, was soon remedied by the man that found Kappa in what remain of a Golden Age ruin. Yuri Sokolov welcomed Kappa into his home, put a roof over his head and offered him a place to stay while he got his bearings. The Sokolovs, merchants by trade and heritage, asked that he work for them to earn his keep. Kappa spent many years with them, becoming a beloved childhood companion of Nadezhda Sokolov, Yuri's young daughter. The situation could only last so long.
His relationship with the Sokolovs became strained as he spent less time working and more time reading and educating himself to the point of neglecting his duties. This did not sit well with Yuri, who had grown to rely on the Exo's work. Tensions reached a head when a workplace accident in the warehouse badly hurt several employees Kappa was meant to be supervising, but was instead pouring over old archives. Kappa felt guilt for the accident and decided it was best he left. He wanted to redirect his attention to discovering more about the past and thus himself. The Sokolovs were not happy to see him leave so abruptly, least of all young Nadezhda, and Yuri in particular accused the Exo of abandoning his responsibilities instead of facing his mistakes.
Regardless, he eventually managed to find work with the researchers of the Tower, working his way up from a mere secretary to an curator, one who finds artifacts in the remnants of the Golden Age. Eventually his potential became apparent and he became a Warlock, and hopes to uncover more about the nature of the Traveler, the Golden Age, and himself...
