SPOILERS FROM THE STORY OF ZEMMERUG ZITSPIKE IN HERE!!
Not much is known about Skullug's history thought he was the only crewbeast on deck along with Kubber during the storm that beached the Midnight Fury. He was almost killed by the slaves but when the ship hit the rocks and fell on its side He along with all the others onboard were knocked out. When he woke up he was questioned along with Kubber and the slave ringleader, Gnarlspike. Gnarlspike was punished and the two crewmembers fell from favour. The day Gnarlspike escaped he was on guard duty, and therefore killed by the slave. His body was discovered by Kubber the next day.
