#hammership

Blacklight the radiant dragon disables a hammership that ventured too close to the Lich's Tear (LA Williams, from Steve Kurtz’s Spelljammer adventure “The Sea of Sorrow,” Dungeon 36, July/August 1992) 

As the battered hammership draws closer, its undead crew prepares to board your own spelljammer (Brom from CGR1: The Complete Spacefarer’s Handbook, TSR, 1992)

DM tip:  If your world includes flying ships, magic carpets, flying brooms, rings of flying, levitation potions, and NPCs mounted on pegasi, griffons, and dragons, then the PCs’ first impression of a big city will be focused on all the activity in the air above.  The most important government, business, religious, and magical locales may be hubs for this traffic.  Also take a tip from Terry Pratchett -- unless the magic college is completely invisible, it may be the most noticeable building as flames occasionally belch out of the windows and lightning arcs from the rooftops, and if you watch long enough the tallest tower randomly vanishes and reappears.
