Play began with the party in dire straits, engaged in combat with the dragon-like creature that absorbed the Ruby of Anarchy after we killed Nathan Gruber. Eventually, the creature tried to run away, but a great shot from Jerrex brought it down.
We descended into the excavation to investigate the dead creature and the ruby. One of the horns was fashioned into a trophy for Jerrex and we salvaged teeth and horns for future use or sale. The Ruby of Anarchy itself seemed far too dangerous to touch, emanating very strong negative energies. Samara was able to read the word, "Passion," engraved on the Ruby in Necral. We also recovered Gruber's spellbook (see below for contents) and a Potion of Invisibility.
After much discussion, we had Exia -- who is immune to all mental effects -- drop the Ruby into the Bag of Weasels. Shortly thereafter, a weasel crawled out of the Bag on its own. Expecting that this weasel was the Ruby, we threw everything we had at it trying to destroy the weasel. Unfortunately, the weasel proved to be indestrucible, but it did climb up on to Samara and turn back into the grain of sand it was originally. With some experimentation, we learned that the Bag will now produce any item we desire with a value less than 1gp in the form of a weasel that transforms into the item on command. It appears, though we are not sure, that the Ruby has merged with the Bag to cause this.
