King Lathas

King Lathas is one of the main antagonists of Runescape's Plague City storyline, which takes place primarily in Ardougne.

At first, it appears that he is initially trying to protect the west side of Ardougne from a plague, and that his evil brother King Tyras is an enemy to Ardougne. Eventually, he persuades the player to murder his brother.

However, it is eventually revealed that King Tyras (thought to be a tyrant) was in fact an ally of the elves and that he is actually a sociopath trying to reawaken the Dark Lord so that he could destroy Camelot.

In retaliation, the player seals off the Temple Of Light to prevent he and the mourners from activating the Dark Lord.
