Skargaroth

Skargaroth was an ancient and powerful god who contributed to the extinction of the Naragi and the destruction of Guthix's homeworld. His dead form is seen as an empty and hollow shell of his body in Guthix's memory at the end of The World Wakes. After Skargaroth unknowingly killed Aagi, Guthix's daughter, Guthix stabbed Skargaroth in his back with an electrifying, god-slaying sword, an Elder Weapon, which killed him and transferred his power and part of knowledge to Guthix. Guthix had then ascended into godhood in a way much akin to how Zamorak would later attack Zaros with the Staff of Armadyl in the Second Age, about 7000 years later.

During the late Naragi God Wars, Skargaroth battled the goddess Tuska and her armies, and was impaled before falling on top of a house. Skargaroth's weight destroyed the house, and Guthix's daughter Aagi, who was hiding inside, was killed with it, which prompted Guthix to stab Skargaroth with his sword.

Skargaroth was attracted to the Naragi home world due to the presence of Tuska. Since Skargaroth was a being that enjoys the thrills of the hunt and wants to take on more powerful opponents for sports, he followed Tuska through dimensions to hunt her down. They met several times, as is evidenced by the 'Death to Skargaroth!' battle cries of Tuska's followers. Due to Skargaroth being a solitaire hunter, he does not wish to be followed, just the next big hunt. Since he has no 'moral alignment' and doesn't require worship, it might be that he doesn't have an associated symbol or set of colours.

When investigating the corpse of Skargaroth it reads "The dead god looms over the landscape, terrifying even in death. His appearance suggests that he was not a benevolent god, though even if he were it seems that none of the gods who visited this world cared much for the mortals living upon it."
