Which also makes sense: all those people ask you for help not just because you're passing by and you look like you can handle the job, or because they've got friends who recommended you to them, but because unlike most of the heroes of Rune Scape, who may be only specialising in combat or technology, you're the MacGyver of Rune Scape- someone who has the skills, has the combat expertise, has the adventuring experience, won't back away from a hard task and knows how to think outside the box.
Guthix mentions that he doesn't want to be worshiped, but his followers should use the environment and not to abuse it, hinting that he acquires his power from the state of the world, whereas other gods gain power depending on followers and the number of artifacts they might have. (Stone of Jas, Staff of Armadyl, ect)
If gods do gain power from their followers, then the main character may have inadvertently introduced Saradomin into existence by mentioning him by name to the first humans in Runescape. In the present, there has been proof that Saradomin did exist, with things such as churches, ancient orders and even an entire religion....so if gods do exist depending on their followers, wouldn't that mean there are possibly hundreds of gods in limbo?
