Tivadar
Tivadar of Thorn was the leader of the Knights of Thorn during the Dark on Dominaria. He led Tivadar's Crusade, a major campaign against the goblins and orcs of Terisiare, alongside Rasputin Dreamweaver.
History
Tivadar was born in the town of Thorn in northeastern Terisiare and was probably disenfranchised by a goblin attack. As a boy of thirteen, he joined the army of the city-state of Ghed, where he briefly served with the apprentice wizard Jodah, who deserted during the Battle of Pitdown. Even as a child, he believed that the wars between the city-states were pointless and distracted humanity from their true enemy, the savage goblins.
Later in life, Tivadar penned The History of the Goblin Wars.
