Helping Orcus become a Deity. Rewards?

[gfishfunk]

In the 5e game I DM, our level 10 Warlock has deceived the party into thinking that she knows the location of a place they can seal an evil dead deity's remains away forever. The Warlock has even convinced the party to let her handle the portable hole that contains said remains. What she is actually doing, is delivering the remains to Orcus (her patron) who will use them in his bid to become a diety. Our level 10 druid (suddenly evil druid) is recently in on the plan after he discovered the plot by accident. Why is a Druid helping bring Orcus into Faerun? Who knows, but we're rolling with it.

What I'm curious about is, what about the Warlock's Patron? How do they feel about Orcus becoming a god?

Patron = Orcus. So, probably good, unless Orcus has dissociative identity issues.
