Kellashen
Kellashen was a behir, a twelve-legged serpentine predator with lightning breath, that occupied the Eastern transit hub of the minecart network for nearly two centuries.
Description
An apex predator approximately seven feet at the shoulder with a serpentine body, Kellashen was drawn to the area by geothermal vents and abundant cave fauna. It exhibited high intelligence, learning to use the rail network for ambushes.
History
Kellashen entered the facility during a seismic event approximately 187 years ago. It eliminated the local Deepwatch garrison and claimed the transit hub as its territory, halting all dwarven operations on the eastern branch. The creature was finally killed in the Junction Hall by a party of surface explorers who used the conductive environment of the hub's iron turntable to trap and defeat it.
