When darkness guides you...

"Feral Greg"

Greggory Lee has been infused with magick from the Dark Crystal. Infusements can have different effects when subjected to different feelings.

For example, when infused with magick from the Fire Crystal, your anger, or control over it, alters how you use it. If someone allows rage to fuel their actions, their flames would burn out of control in a blaze of chaos, while someone well in control of their anger could create focused pillars and shards of flame that they have total control of.

Anyway, back to Greg.

Darkness reacts to instincts. Whenever Greg's fear or anger reaches the point where his body cannot stand it anymore, he enters an almost feral state where his magick guides his actions in a bid for survival. This ferocity comes at a price, as after a short time like this, Greg will pass out from overexertion.

While in this state, Greg's only focus is keeping himself and his allies alive. This can lead to some brutal reactions, such as ruthless takedowns of enemies.
