Castle Dreams (Castle Perilous‪)‬

Everyone is in line to the throne of Castle Perilous in the series that's "thought-provoking . . . crazy . . . weird . . . [and] unexpected" (TV Tropes).

Who will claim the throne now that Lord Incarnadine, King of the Realms Perilous, is dead? Under a mysterious spell cast by a mischief-maker, all of Castle Perilous's 144,000 creatures of curiosity clamor for the crown. Outside of the castle's coveting fray, Gene flies off with an adventurous Amazon in supernatural manifestation and Lord Inky explores the dark mysteries that lurk in the realm of the dead!
