Beneath the Radiant Dome

Old-Schoole Essentials Scenario by Necrotic Gnome

A prismatic-hued dome stands alone atop a desolate, long-forgotten plateau. An open archway tantalisingly beckons wanderers within. In the dungeons beneath, adventurers may plumb caverns haunted by dimensional monstrosities, explore wizard labs warped by ancient magic gone awry, and uncover fabled arcane relics of lost technology. Only the bold and cunning will emerge intact!

  • A science-fantasy dungeon adventure designed for 6–8 sessions of play.

  • 83 keyed areas over two sprawling levels.

  • Suitable for around six characters of 4th–6th level.

  • Easily integrated into any campaign.

  • Ready to play with minimal prep.

Beneath the Radiant Dome is a deluxe revised and expanded version of Gavin Norman's dungeon delve of science-fantasy weirdness, originally published in 2012.

Beneath the Radiant Dome is available in PDF through DriveThruRPG
