Capture of Caernevros

Caernevros, also known as the Tower of Carnage, was assaulted by in July 2435 A.G. at the same time as the Battle for Rangrim's Wall. It involved several adventurers against the Grimlock forces of the Ilithid  Gren'Nerdum, as well as several minor ilithids and a couple of Intellect Devourers.

Result
As a result of the battle, Caernevros was cleared of evils and restored as Whitehome, of which Lady Tiasal Viliadul took command of. The barbarian Varric Galanodel was slain in the battle, his brain consumed by Gren'Nerdum, who shortly after fled the battle via a Plane Shift spell.

When Gren'Nerdum fled and his fellow ilithids where slain, they lost control of the commanders at the Battle for Rangrim's Wall, who they had been mind controlling, leading to the army fighting itself as well as the armies of Rangrim's Hold.
