Erpham Warrick of Bright Tree Village built the battle wagon to defend against the forces of a tribe of Duloks with whom the Ewoks had a long-standing feud. When Dulok warriors arrived in the forest and sought to destroy the Ewok village's Soul Trees—objects of great spiritual value to the Ewoks—Warrick commanded the battle wagon and drove the aggressors from the battlefield. The weapon proved instrumental in ending the conflict in the Ewoks' favor, forcing the Duloks to remain in Endor's swampier regions. However, as the years passed, the Ewoks largely forgot about Warrick's massive siege engine.
