「⚔️ ; Aʙʏss Kɴɪɢʜᴛ 」

Why, do you ask? For that his canon (with tower of disappearance in mind), he sacrificed himself to give the other Chasers enough time to escape. Though, despite having used most of his magic there, before he ended up dieing, he used what he had left to teleport himself out. Though, it was believed that he did die until he showed back up a few years later to Kanavan. 

His sight is very sensitive to his own magic. Due to that, he will not use his powers unless he’s to his own physical limits- out of fear that using too much of it once more will take his sight from him for good. Not that he expects having to be forced to use it, he just wants to prevent that from happening.

As for others’ magics, he will react to them differently- flinching slightly until his mind registers that it means no harm if it’s from someone he trusts. As for someone that desires to harm him, he will register it as a potential danger and will become wary of it.
