Viollfest is a celebration held in honor of the Elder Giant Violl Forte held from 8th Solatine to 21st Solatine. It initially began as a formal dinner celebrating Violl's rebirth as an Elder Giant, as well as his victory over a large horde of Beasts, but at his request became far more of a party - with his thinking being that such a celebration would help to raise the morale of the Garden's people.
While full of activities, the festival is best known for its tournaments - where people from all nations compete in battles to be crowned royalty for a day. To his own dismay, Violl is only allowed to spectate these, and not participate.
