An old character background

The day of the graveyard battle. I (Dewglass) came to Eastgate after years of tutelage under the Omnithrox of Aphasia.  My master told me that if I were to retrieve three of the Ioun stones, he could show me how to create a philter that would grant me immortality. Of course, I have already discovered (through auguries to Tiamat), that the Omnithrox's heartblood *is* the secret ingredient, but the Ioun stones will get me a more private audience.  I'll still need to find an enchanted dagger to remove all of his hearts.  An airship from the Lakbunish Protectorate was reported missing in this area a century ago, so Eastgate is a good place to start.
