Querelian

Querelian was an eladrin soldier from the Feywild.

Querelian's War
He fought alongside his wife, Omaphara, against the werewolves during the War of the Pelt. Though he survived the war, his wife was slain battling the werewolf lord, Viktor Mazan. Querelian was furious when the Court of Stars sued for peace, believing that the werewolves should be exterminated. Swearing that he would make the werewolves pay for her death, he formulated a plan to murder Viktor Mazan and frame the eladrin city of Mithrendain, providing the spark that would reignite the war and see the werewolves destroyed.

His plans were ultimately undone by his wife's spirit, who had come to believe that while the war had been justified, restarting it would cause unnecessary bloodshed. Informing the Challengers of the Unspeakable about her husband's plan, she gave them her longsword, Moonclaw, and begged them to stop him.

Though Querelian had already sent ravens to Mithrendain calling for troops, the Challengers were able to defeat him and save Viktor Mazan before their arrival; once the adventurers explained the situation, Querelian was taken back to Mithrendain in chains. As a further sign of good faith, the Challengers also gave them Moonclaw.
