Tirion Cayde's father was a paladin of Pelor, and his mother was a cleric of the sun god, the sister of the duke of a minor duchy in the Kingdom of Furyody. When both his parents were killed in an undead scourge, Tiron was taken into the ducal household and raised as a son alongside the Duke's heir. Tirion followed in his parents' footsteps and dedicated himself to Pelor as a cleric. With the untimely (some speculate suspicious, but those are just unsubstantiated rumors...right?) death of the duke, thw duke's younger brother convinced the duke's advisors into a political coup, removing the duke's rakish and ne'er-do-well son and placing the duke's competent brother on the throne. The son immediately started a rebellion against his uncle, fleeing to the forest. Tirion supported the rightful claim of his cousin, perhaps a bit too vocally. His superiors in the church were afraid the new duke, never an ardent supporter of the faith, would punish the temple. For his own safety and theirs, it was "suggested" that Tirion should go on a traveling missionary journey. Preferably far from the duchy. Tirion eventually ended up in the Free City of Greyhawk when the depradations of the Slave Lords were at their height and was recruited to accompany the adventurers in their expedition.
