The Empyreans will eventually be featured in a proposed Champions setting book, tentatively called "Lost Worlds" or something like that, which isn't on the pub schedule yet. I'd like to see it in '05, but we haven't got a firm schedule that far out. However, there are plans afoot to use some of the characters and setting before that, so keep watching the skies. (Also, another Lemurian villain, Leviathan, appeared in an issue of Digital Hero, and more Empyreans may show up there eventually because I'm awful fond of them.) dw
