A demon was attracted by the stench of the dead people whose lives Einya had snatched, and offered to make a pact with her. Einya didn't so much as lift an eyebrow. "No. I will not give you my heart. Or my soul. But I'll let your heart be inside me, like a parasite." Einya's terms were less than ideal, but the demon felt that forming a symbiotic bond with Einya would be a delicious thing indeed. With some reluctance, the demon became a part of Einya's body and let her wield his powers.
