Dyr, who appeared in the Sunbird legacy book, Was an ancient warlord who, like so many others, tried to grab the power of the universe for himself, but before he could enact his plan, the sunbird was dismantled and sent to the four corners of eternia. Skelator, learning of his legacy, goes to retrieve the four pieces, and use it for himself. He looks very much like very much like Skelator, Im sure you could use the SLL boots for him. Just think he would make a cool character for the series, down the line, after the big guns are out of the way.
