Born in Aren Mador in Essenia, now modern day Far Madding, he was one of the most powerful False Dragons on record. After he was captured his followers assaulted Tar Valon in an effort to rescue him.
When Ba'alzamon speaks with Rand al'Thor in his dreams, he tells of the White Tower using False Dragons such as Darksbane, Davian, Yurian Stonebow, Guaire Amalasan and Logain Ablar. Thomdril Merrilin recognizes the names and knows that even speaking them is dangerous. Rand says that he will not be used by the White Tower, Moiraine Damodred, Siuan Sanche or Verin Mathwin, like Darksbane and the others were used.
