King Ixilthetocal

King Ixilthetocal is a sahuagin in the Underwater City, encountered during Chapter 4 of Baldur's Gate II: Shadows of Amn.

Involvement
King Ixilthetocal is the ruler of the sahuagin in the Underwater City. He can only be encountered if the party accepts Saemon Havarian's offer of help after they escape from the maze below Spellhold, during the quest Escaping the Asylum.

If the party goes through their initial conversation with Priestess Senityili peacefully, they will be taken to King Ixilthetocal for an audience, and this will start the quest The Prophecy of Sekolah. Once the party has proved their usefulness by defeating an ettin, the King will ask for their help in eliminating Prince Villynaty, the leader of the sahuagin rebels.

In the King's possession is the Magical Rope, an item required for the party to leave the Underwater City. Resolving the sahuagin conflict is one way for the party to acquire the rope, but they can also simply pickpocket it from the King or kill him for it.

The King also has the treasury key, which can also be pickpocketed from him. This key allows the party to pillage the treasury, which contains another copy of the Magical Rope, the Rod of Lordly Might, the Gauntlets of Crushing, and the Sahuagin Scribe's Notes.

If the party helps King Ixilthetocal kill Prince Villynaty, he will reward the party with the Magical Rope, the Rod of Lordly Might, and the Gauntlets of Crushing, before leaving the area for good.

If the party agrees to help Prince Villynaty kill King Ixilthetocal, the King will be replaced by a second copy who is armed with the Impaler.
