One of the oracles of the Trolls. Like his sister Khasaanda, he was blessed with the gift of Seeing the future. Unlike his sister, Krellenos was showered with praise. When Drakath made Krellenos his newest Chaos Lord, he used his reputation to hide in plain sight while spreading Chaos among the Horcs and Trolls of Bloodtusk Ravine, until he made the mistake of chaorrupting his little brother Antiphuus, which would turn his sister against him when she found out the truth about him.
- According to Quibble, Krellenos is pretty clever. He went to work chaorrupting Horcs, Trolls, alliance soldiers, and animal hybrids alike, and nobody but Bachius suspected a thing about him.
- He is also the fourth Chaos Lord to act like a monster, the first being Vath, the second being Ledgermayne, and the third being Tibicenas. He Chaorrupted his own brother Antiphuus, whom the players knew they had to kill while hoping that Sokrakiis would understand about it. He also stole the Accord of the Dark Sun, and later began chaorrupting Horcs and Trolls alike, forcing Kagg and Sokrakiis themselves into a meeting, and laughed about it. He later went on to attempt Chaorrupting the Arashite Ore of the ancient temple, using a Serpentress to do so which transformed the Serpentress into the Gruaige Baas. Kagg later blamed Krellenos for Antiphuus' death.
- Krellenos is killed by his sister Khasaanda, making him the second Chaos Lord to be killed the first being Ledgermayne.
