Cyan, my rather old character.
He knew the times before the Last City, and because of this, he does not even remember how many reboots he had. At some point in his life, he completely lost his body, and a certain "well-wisher" made him a new one, while leaving a couple of "gifts".
Actually, after that, the already shattered psyche of Warlock was finally broken, he became addicted to harming himself, after which he repaired himself live.
In fact, he is completely closed from everyone. He, like any warlock, is greedy for new knowledge, but most of all he is interested in transferring consciousness from his body back to a human one, we can say that he is obsessed with this, because existence in his current body only brings him pain.
