During the Second Shadow War, Asmolum uncovered the nature of the Yalaini crystal array that became Bael'zharon's prison. He discovered that one crystal, recovered by the Yalaini on Aerlinthe after Bael'zharon's imprisonment was taken to the Nexus Facility for safe keeping. He learned there were six crystals total of which five were recovered by the Yalaini. The sixth was The Great Work at Frore. Through later investigations, he located the three Vestibule Crystals though he was unable to enter the Vestibules themselves. After these three were destroyed by the Isparans, Asmolum discovered that the final crystal, the "Shard of the Herald" was within the Ithaenic catacombs down Kelderam's Path. This knowledge was influential in the Dericost defense plans. Asmolum was intrusted to keep one part of the key to Kelderam's Path. But he was slain by Isparans and the key piece was taken from him.[4]
