From the computer to the tabletop, this is all about games. Updated each week-end.
Some classic Dragonlance art here from Keith Parkinson (RIP). This will always the the flying citadel in my mind, the title comes from the D&D adventure this art was originally used to illustrate.
The flying castles were a sorcerous invention to gain air power and move the evil armies between locations quickly and without worrying too much about supplies. This art sees the flying castle looming over a group of heroes in the foreground, and of course there are dragons keeping the castle company.
