Zuul

Big bipedal lizard head of an underground arena in the Shark's Tooth. He needs a hero-- could it be you? One of many after Nightscale's Aegis. Made Lankin his champion after Lankin defeated his serpent in an arena battle as a test. Leader of other cave-dwelling creatures who were also sent on missions to get the Aegis. Offered to aid the party in taking down the dragon...if we could only come up with a plan.

Description
Lizardman dude of some barbarian flavor. A big, fighty guy, if you know what I mean. He did not initially have red eyes, but was able to initiate those in combat with the party.

Background
Zuul was the leader of various cave-dwellers, mercenaries, and other explorers who had also come to the Stone Tooth seeking out Nightscale's Aegis for themselves. Too weak to accomplish the deed on their own, they banned together under Zuul's, the mightiest, command.

It is as yet unclear if Zuul had always been under the mountain and became a Red Eyes or if he was sent there on a mission from Durnen. Much of his background also is shrouded in mystery.

"Thanks for the Memories" (1x22)
While negotiating their way into the Stone Tooth, the party heard Zuul's name mentioned as the leader, either of the orcs or another group. He seemed like the boss of the place, and the group wondered if maybe he was working as a henchman for Nightscale.

"I've Got Headaches and Bad Luck" (1x23)
Erfwe said the party (after they'd burst into his rooms) were probably here to fight for Zuul "in the glittery place" given Zuul's interest in acquiring a new champion. Going deeper into the caves, the party encountered Zuul in the flesh (scales?), a giant lizardman with two equally giant axes strapped to his back, giving orders to his fighters in a crystal-studded arena known as the Glittering. Lankin fought a monster in the Glittering, earning himself the title of Zuul's champion and the party Zuul's agreement to collaborate to take down Nightscale.

"We've Got a Big, Big Mess on Our Hands Tonight" (1x24)
Zuul shared some information about Nightscale with the party and said they were welcome to investigate the rooms below, but that his men had not been able to find a way deeper down to the dragon's lair from there. The party went, not thinking to ask if Zuul knew another away down. Hijinks ensued.

"Trying to Hold On, Didn't Even Know" (1x26)
Wounded and exhausted after battling Nightscale and successfully removing the Aegis, the party followed a river out of the mountain and found Zuul waiting for them. He'd known how to find the party after Nightscale had fled through the hole, alerting him and his men to their likeliest escape route. He had also seen Nightscale bereft of the Aegis, so he knew the party had it. Negotiations once again quickly broke down, despite Zeno's best deceptive efforts, and tensions rose as Felegum worked to complete his dome spell to buy the party time. Zuul revealed his red eye trait and the party was able to win this round of Felegum defense. The dome went up and Zuul backed off.

"It's Easier to Run" (1x27)
Through stealth, illusion work, and using the forest around them, the party managed to get a lead on Zuul and his cohorts before the dome dropped. Sneaking around the side of the mountain, they discovered their cart where they had left it...except in possession of Zuul, who was in the middle of butchering their horses. The party did not remember this until later, but their tablets were on the cart and thus were once again in possession of Team Red-Eye. The party ran and ran, pursued for what felt like days by Zuul's men.

"Things Are Better If I Say So Long And Goodnight" (1x28)
Reaching the town of Splinterwood, the party decided to make a stand in the middle of the town square. Zuul brought an impressive contingent of brawn with him and once again, battle was joined. Again, Zuul demonstrated his ability to make his eyes go red on command. After heavy injuries on both sides, Zuul went down-- only to escape as a ghost and be punched by Harry, who had conveniently just learned how to fight ghosts. Helli went through Zuul's body's pockets and found the tracking device Zuul had been using to follow the party via the Aegis. Ghost Zuul was very slippery and would have gotten away, if not for Helli's extreme accuracy and reach with her Wand of Magic Missiles. The orcs who had accompanied him shouted out "The Stonebloods are free!" in joy and Helli earned the title of Zuulkiller.

"Set My Clocks Early 'Cause I Know I'm Always Late" (1x29)
Further examination by Helli revealed that the stone tablet Zuul carried was indeed attuned to the Aegis but its enchantment was now broken on finding its object.

Durnen
a big unanswered question: how do these two know each other? Or are they just coincidental red eyes?
