Xau-Tak

Xau-Tak is a god mentioned by V during the Hero's Welcome quest. V claims to have visited at least one world they were active on, and compares them to Bandos, Tuska and the Queen of Dead. V describes the planets they've been to as a "sea of corpses".

While not known to have ever been to Gielinor previously, V states that Xau-Tak's tendrils have taken root somewhere on Gielinor after the Edicts of Guthix were broken at the start of the Sixth Age.
