I like it.
I can see the adventure now. Your bold explorers have to navigate across the tortured, rain-slick stone of a shattered dungeon while over-head, piercing the brooding, lightning glutted clouds is the Thunderspire itself, clawing at the heavens. Peals of thunder echo across the Labyrinth, and the land beyond, accompanied by wailing winds like the very damned souls of Hell!
The secret to the adventure, of course, is that at the top of the 'Spire is a bard, or rather The Bard (no, not Shakespeare) in his new, long-haired, spiky-leather image, strumming his axe/guitar to the accompaniment of the storm.
Top stuff.
