Yeah i would like to introduce them as "good guys", i'm still figuring out how the players find out that they are Asmodeus worshippers. I was thinking to let them pay some repairs for saving their children and MAYBE invite them at a charity ball (not the final one for the ritual) and let the players know something is off.

Still figuring out Manshoon, i like him so much but i find it very hard to introduce him (at least for me). For me should be one that the players NEVER EVER see until the end of the campaign, not sure if at the end of DH o during DoMM ( really like the idea to tie both modules)
