King Thoros is the new king of Ardougne after King Lathas is killed during the Song of the Elves Quest.
During Song of the Elves, NPCs in the quest only refer to him as "the new king of Ardougne." He decided not to send troops to assist the rebel elves/dwarves during the siege of the Temple of light towards the end of the quest.
If the player attempts to talk to him, he will thank them for their assisstance in overthrowing Lathas but declines to speak further, as he says his predecessor has left him with a lot of work.
He is also involved in Dragon Slayer II if the player has completed Song of the Elves.
- In RuneScape 3, King Thoros is the cousin of King Lathas. However, in Old School RuneScape this has not been confirmed, as Thoros simply refers to Lathas as his predecessor.
