The Windlord was, at one point, an Elf, though his Tribe is a matter of debate - the WindLord is an albino and mostly a BastardElf. Without doubt, he is now a debased creature of Iron and has further created an entire Tribe of perverted Elves, the Goblyns, to be his slaves.
Once he was a Savant who was exiled for probing too deeply into the structure of the Worldstree. At first, he befriended an extraMythic being who was accidentally flung into Worldstree. The WindLords protected this creature, a Shivan Scientist, from the Savants who sought to destroy or banish it. Later, with the Shivan's aid, he devised a means of deliberately opening Gates, supposedly to send his friend back home. In the end, the WindLord, in his arrogance, became obsessed and sought to use the Gates to other Myths for personal gain. It was his belief that the opening of such Gates is unavoidable, and should be controlled as much as possible (by the Savants, of course). Now his revenge is complete: each time one of his Lightening Bolts strikes the Worldstree, a Gate opens for however brief a time. This does not endure him to the Savants, but has in fact forced them to confront the Nature of Worldstree.
The Windlord lives in a "volcano" in the Ringwall Mountains, at the East Pole. This volcano continuously emits great clouds of Steam that are responsible for most of the rainfall in Worldstree. Before the Windlord, the Weather was a matter of clockwork predictions. Now it is Chaos. His Lightening bolts strike dead the Eldest of Trees (and Dryads) and assualt the Worldstree itself in yearly Storms of incredible violence.
