Bothorion had been fairly quiet for months, with the Eldar having ensured the Orks stayed away from their sacred sites and the Orks content to leave the Eldar in peace, given their numbers and the high cost of prosecuting a war on Tarsis Major. However on 0912.008M42 Warlord Nazghat returned, angry and determined, and ordered the Eldar to be removed from Bothorion so that the world could be geared up as a base of operations for the upcoming war in the Mabb Nebula.
The Orks were galvanised into action, and with Nazghat leading them a mighty Waagh! fell upon the sparsely defended Eldar positions. Surprised, the Eldar fell back but to their credit were able to respond with a meaningful counter attack late on 1012.008M42. However luck was with the newly enthused Orks and nothing the Eldar tried seemed to pay off, the Orks could not be stopped. Rather than continue the bloodbath the Eldar vanished via thier webway network, allowing Nazghat to begin construction on his new prize.
