The first few wars between the crews ended in a stalemate, and parts of The Asylum to split due to disagreements over pvp and war policy. The eventual Horsia War occured when they declared war against the remains of The Asylum, and their allies.
Although they had far fewer numbers, Horsia managed to hold their own against the other crews, especially as their fighters were better trained and organized. However as the war continued, The Asylum and Coalition learned to adapt and train their fighters too, and so many skirmishes were fought whereby there was no clear winner.
In the final few weeks of active fighting, Horsia resorted to guerrilla warfare - using hit and run tactics which they largely still use.
The war is currently on hold, as Horsia have been very quiet lately. Skirmishes still occur from time to time.
