Donellan's Day was celebrated annually, and traditionally included events like rake-riding, during which uvak wranglers would fight to the death in the Korsinata. During the event, the High Lords of the Lost Tribe would decorate their private boxes, often trying to outdo one another.
On Donellan's Day in 3960 BBY, Campion Dey attempted to assassinate Grand Lord Lillia Venn during the rake-riding competition.
