Wanna know why Eden always wears long sleeves and gloves?

Because his magic is slowly killing him :)

I shall elaborate

Abyss Magic is an artificial form of magic, so whenever a mage uses spells, it affects them too and covers their body in a dark thing the creeps up to their upper body; severe cases even lead up to the lower jaw

Think asta from black clover

The stronger the spell, the faster and more severe the curse
