If anyone else has the urge to use Descent (and maybe other Terrinoth games) for roleplaying adventures or already does I've started exploring using Genesys for this ahead of the upcoming Terrinoth sourcebook so if creating or playing Descent / Terrinoth RPG adventures sounds appealing here's where we can begin...

My first RPG offering's up now- the beginnings of it at least- it might inspire some campaign creation that you want to do for Descent or Genesys too (I'm hoping to make it both an RPG and a Descent campaign if I can figure out some spoiler prevention and it ultimately works- may be different parts of the story in each or deciding spoilers are acceptable!)
