The party's floor-five opponents — desert sky-castle gnomes whose Wasteland Fortress the crawlers must storm in the Air Quadrant.
The Dirigible Gnomes are the opponents Princess Donut's wheel-spin assigns for floor five, in the Air Quadrant. To pass the level, the party must storm the gnomes' sky-castle, the Wasteland Fortress, in a dune-swept desert landscape — one of four possible opponents (alongside the Razor Fox Kite City, the Nightgaunt Precipice, and the Great Dirt Island of the Wind Sirens). As the floor-five door opens, sand cascades into the antechamber on a harsh, hot wind, previewing the desert war to come.
Carl is quietly relieved they didn't draw the Nightgaunt option (his cloak enrages Nightgaunts), and Donut is gleeful: 'Come on, team. Let's go kill some gnomes.'
Gnomes of a dune-swept desert floor who command a castle in the sky, the Wasteland Fortress.
The floor-five Air-Quadrant opponents, holding a sky-fortress the party must storm.
