War in My Heart

Lilith and Genesis hate each other. So of course, they get paired up to go searching for the leader of the Nephalems. No one knows who it is. What everyone does know, though, is that whoever it may be is leading a rebellion. A rebellion that could lead to a war and thousands dead. Will Lilith and Genesis get over their hatred for each other and focus on the mission? Will some other feelings develop during the search?

Context: A Nephalem is a powerful being that is an offspring of an angel and a demon, resulting in a hybrid.
