Ok. Game is done, effectively.
...
Garagos can make a DC18 Will save.
I made a roll for Jillian, but did not succeed, but I really only singled her out for the soulsuck because she was inactive, so I am overturning my roll and saying that she is trapped in the gem. It's good to be the DM.
It has been fun, interesting, and scary all in one. Perhaps we'll meet again in another game. I will pass on the 4e game. I do not own any of the books and when I played a module when it first came out I didn't care for the system. Maybe I'll take a look anyway.
