My story is about my cleric, Clarke.
As our party neared the end of Red Hand of Doom, we started to get hints that we were going to have to fight "Tiamat" (our characters, obviously didn't know it was just an avatar), and my character - a follower of St Cuthbert - was intent on either destroying her or sacrificing himself trying, but had no ideas as to how this would happen.
The artificer in our party knew exactly, though. During the combat, he ran to me and handed me his portable hole, and told me if I wanted to save the world, I'd have to run up to Tiamat and stuff it inside my handy haversack...
Which I did (barely surviving the attacks of opportunity), and pulled the avatar and my cleric both into the astral sea, where legend in Brindol has it they both still exist, forever chasing each other.
