Volkar Civil War

The Volkar Civil War, rarely called the Great Sundering (but not to be confused with the Great Sundering) and contemporaneously called the Ukna-Siplim War, was a conflict primarily fought between House Ukna and House Siplim which divided the Volkar Stellar Imperium from 2267 to 2272.

While the Imperium had experienced numerous Sunderings throughout its history, few had been so expansive as the conflict became by the middle of 2268. Every House in the Imperium was drawn into the conflict by the beginning of 2270, mostly as a result of an Imperial proclamation issued in mid-2268 declaring House Siplim to be in open rebellion. This proclamation pressured non-aligned Houses to declare for House Ukna or be likewise declared as rebellious.

Though House Adel fell to an Ukna-Imperial force in early 2270, House Siplim's control of the vital Fouahiri Strait, which connected House Siplim's territories to those of the rest of the Imperium, ensured that no further advances could be made. By the beginning of 2271, after several failed attempts by the Ukna-Imperial-Julau alliance to take the Strait, the war came to a stalemate.

In order to end the war, the Emperor permitted House Siplim to survive, though control of the Fouahiri Strait was remanded to Imperial authority. House Adel was permitted to survive and maintain its territories, but dismantle its defensive platforms. The leader of House Siplim was imprisoned by House Lishval, and his children were disinherited. Control of House Siplim was passed to a young nephew of the former Duke, with a regent recruited from House Lishval to guide him.
