The immortal mummy and God-King of the Sandsea. Sek Duat is an immortal mummy lich who was blessed with eternal life yet cursed with being undead and poses as his own heir time after time. He knows more about the Sandsea than anyone, thus why the players and Zhoom track him down to seek advice from him on how to combat the power of Zahart's Djinn Tibicenas.
To get the advice they needed, the players had to chase after and catch Sek Duat by participating in the Carpet Chase minigame after fighting through his army of Mummies and Anubis Deathguards. After catching him and afterwards interrogating him (even at one point thinking about trading him to Zahart himself for something unless he told them the way to defeat Tibicenas himself, which of course frightened him because he was afraid of him), he would finally reveal that the only way to defeat a Djinn was with another Djinn, and he believes that he knows where they can find one.
Leading them to the Cave of Wanders, he stands by as the hero and Zhoom clear the path to the lamp containing a supposed Djinn and show it to him. Unbeknownst to the two, however, Sek Duat is secretly planning to steal the lamp and use it to rule the Sandsea for himself.
- He originally appeared in DragonFable where he was also an NPC, as well as a fightable enemy. In AQ Worlds, when you first encounter him, you play the mini-game and chase after him to finish the race before he escapes. Later on, you'll get to fight him for real in the Cave of Wanders.
- His mask is available as a helm in the Sandsea Reputation Shop, which you can buy once you are at Sandsea Rank 8. His cape and armor are item drops from his monster self in the Cave of Wanders.
- When he was designed for AQW, his artwork was based on that of the very first lord of Chaos Escherion. He has the same monster animations as Escherion, too. This makes Sek Duat somewhat of an Escherion clone. Also, the Sandsea is connected to Chiral Valley from Mobius, where Escherion is encountered, so that makes plenty of sense.
