Metaphysical / Paranormal event
Bregan D'aerthe played a role in the Drow attack on Mithral Hall in 1358. After the battle was over, it was assumed by many that the illithid advisor to Matron Yvonnel Baenre, Methil El-Viddenvelp was dead. In truth, Jaraxle Baenre and Kimmuriel Oblodra brought the badly injured creature back to Menzoberranzan. The creature served as an advisor to Bregan D'aerthe and a psionic mentor for Kimmuriel.
