About the dragon weapons coming from Freneskae, here's my theory. The dragonkin were here in the beginning. Whether the myth about them being here before Guthix itself is true or not, they, as a race, were here before all others. I believe the elves were next, but that's not the point. Then the mahjarrat, under the control of Icthralin, come. There are other mahjarrat as well, Armadyl and Saradomin come to mind, but as of now they aren't important. At this time, like the elves, the gateway to Freneskae from Gielenor, and vice versa, still stands. The mahjarrat find the fabled race called the dragonkin, and somehow harness their power. They go back to Freneskae, and using tools only found there, smith weapons, and put the power of the dragonkin in it. Whether it was the Mahjarrat or the equivelant of dwarves on Freneskae who actually smithes them, it doesn't matter. The Mahjarrat return with the weapons, thousands of them. And now all that is left is buried in the sand of the desert, or in keeping of pwoerful beings. How the dragon weapons are connected to the dragonkin? I do not know, although it is safe to presume that if a dragonkin who lost his strength from a weapons lived on, he may have some sort of connection to the very weapon he 'made' I could be wrong though :P
