Jake is an adventurer that worships Guthix, he likes to steal difficult-to-get bounties, he appears in Gielinor and Future RuneScape timelines.

Outfit and Appearance
Jake looks the same in both timelines, he has brown hair, he is tall and uses a white and green shirt, blue pants and white shoes, he fights with a Rune shortsword and a Book of balance spells, which he uses to cast Claws of Guthix, an useful spell to grab things and reach places, and also breaking people's bones, of course.

Gielinor
In Gielinor, Jake is always wanting to help people, and sometimes likes traveling around the world, in his travels he often enters abandoned temples and steals something.

He doesn't seem to have someone to help him in his adventures, but everywhere he arrives, someone greets him, he seems to be a very kind person.

Future RuneScape
He is not actually named Jake in this universe, no one knows exactly his name, not even himself.

He still travels around the country entering Zamorakian temples, giant castles and luxurious palaces in the search for adventure and treasure, he once even broke in the Seer's Tower to steal Guthixian objects.

He also helps fighting the evil forces, and clearly hates Cain and the Outlaw Horde.

In Gielinor
Jake finds out about the Fist of Guthix, and decides it's time to get more powerful, he then decides to get one of those charged stones and take them to the Void Knights, the ones he consider that are the wisest of the Guthixians in Gielinor, when he has done this, he will get his Balance book charged with the Fist of Guthix energy, and he will then return the book he borrowed from the library (G: The Strongest Fist).
