I remember reading somewhere that Guthix FOUND an empty plane (Gielinor). Yes, then shaped it into the world we roam today, right? Indeed, so I doubt he is the son/daughter of an Elder God. I agree that it's unlikely. If both his parents were Elder Gods Guthix would have been one too, and if only one of his parents was one, then where is the other God? Of course it could have left together with all the Elder Gods... Assumptions, assumptions. Sources tell us that Guthix indeed found this plane, although empty, and that he populated it himself. The Elves arrived through the World Gate, and the Humans through the Portal of Life etc. etc.. I don't think it's clear whether Guthix found only this dimension, or that he found this planet. The only things we know for sure is that the Elder Gods created Gielenor (the planet or the dimension?) and that Guthix populated it and brought life to it. The reason why the RuneScape Wiki says that Guthix actually can't create planes/planets is purely logical: Why would he populate a dimension someone else made instead of creating his own? I must admit that I too assumed Guthix's limits this way, though it's far from certain. One thing does come to mind now, said by the Queen of Snow: "The Land of Snow was created aeons ago by Guthix, as part of his balancing of the world. The coldness of this place counteracts the heat of the great deserts and volcanoes of others, ensuring the correct balance of hot and cold." As with other sources, this can be taken both ways. By 'created', does she mean Guthix created the whole dimension? Or did he just find an empty plane and decided it should be cold there?
