Sar-Elam was a human wizard who became the Seventh Dragon. Sar-Elam's sacrificing himself to repel a demon incursion moved the conscience of Asha, the Dragon of Order, who then bestowed upon him knowledge of the nature of matter, spirit and the higher path of power. Enlightened by his new understanding, Sar-Elam ascended to Dragonhood.
Ashan was once plagued by Urgash's demon armies, who waged bloody wars with Asha's children. Intending to end the wars once and for all, the Great Wizard Sar-Elam and his disciples, by sacrificing Sar-Elam himself, ultimately sealed the demons away in Sheogh to prevent their return.
Until the Wars of Fire, little were known of the elves. It was they, however, who first summoned forth the other races to do battle against the demon armies; many of the great generals of that war were elves. It was the elves who held the line against the last demon assault as the Seventh Dragon prepared his final spell, not that men remember this now.
