Hate to tell you, Shawn: the floating globe is not mentioned in the write-up on Azun. It's not in Bill Keith's drawings either. I _have_ written to Michael Dooney to ask if he remembers, though!
Hi! Michael wrote back and (after giving me permission to use the Azun cover) said:Those other images of the buildings done by Shawn Driscoll are really nice.In my mind at the time,those spheres were supposed to be giant anti grav transport spheres ;)
