Looking for a smut work about a kind necromancer

Heya! Might be a long shot, but I’m wondering if anyone else read this story and could help me find it.

I remember this necromancer is the main character, he makes pacts with the dead to help resolve the reasons they’re still hanging around, and in return he can call on them if he needs help. Being a necromancer makes him shunned from the magical community, at least at first. There’s a vampire who he ends up rescuing from being enthralled, something about her being especially powerful or special? There’s a witches coven that gets involved as well, sort of a magical turf war as a result of him getting involved in the community.

If anyone wants more details, feel free to ask some questions and those questions might spark my memories of the plot so I can fill in any holes that might prevent you from helping.

Thanks in advance, even if I don’t end up finding the story :)
