Deeper and deeper the Collective goes.  Down farther into the Underdark, they happen across a chamber owned by a Mysterious Warrior who challenges them to a battle, not to the death, only to discover, upon beating the warrior, that he was in fact Krim Ja'ak 'The Fates Maul' an ancient and powerful brass dragon.  The Collective became the first mortals in hundreds of years to lay eyes on a dragon.  Krim Ja'ak asked a favor of Alkahest before the Collective continued on their way to find the Glass of the Mind of Ioun.
