My House Tersius campaign is going brilliantly. Over the past few sessions, we've had the following series of events.
First, House Venture hired my crew to rescue a young noblelady who's being held hostage in an Elariel manor.
Kobe responded by seducing Shan Elariel in a most interesting Mental Conflict and winning an invite to the Elariel manor where the hostage was being held. Then they used Spirit to establish that there was a secret passage leading out of Kobe's bedroom, tricked Shan into bringing the hostage in, killed Shan, and escaped.
When House Elariel got wind of what happened, they sent assassins against Melenius. Mars held them off but almost got killed himself. The crew retreated to Tersius lands in the West.
While there, we stirred up a fascinating bit of backstory. Apparently, Kobe Tersius and Allriane Cett have a sort of "lady's agreement." They keep each other's secrets, and have pledged that if House Cett collapses, Kobe will get Allrianne married into House Tersius, and vice versa.
