"It will! I will grant you sight, but it will take time. But since you have accepted my offer..." And really, even for a scared mortal, it was a fairly quick decision. Abysa does have a little voice in his head that tells him when something is a foolish idea, but he ignores it for this situation. Micolash's whimpering is heartbreaking, not to mention the state of his physical form, not to mention that the demon does still blame himself a little for allowing such a catastrophe to happen.

"Ah, keep in mind, this means part of my magic, generated by my soul, will be siphoned to you in the form of a healing mark. It will be as so until your eyesight is restored, in whatever way that is accomplished. We could seal it with a kiss, if you like. I do not think a blood pact will be necessary or a good idea." Actually, it's a good idea to keep as much blood in Micolash as he can.
