On the northern side of the Nysanna Range, where water and force leylines intersect, lies the Inthikrilix Dungeon—a massive fortress carved into the mountainside. This network of ice-encrusted tunnels delves deep into the mountain, leading eventually to the crypt of Inthikrilix, an ancient mage who mastered both ice and force magic.
The dungeon is guarded by spirits of ice and force—ethereal beings created by the leyline convergence or bound by Inthikrilix himself. These spirits manifest as crystalline wraiths that can freeze flesh instantly or crush intruders with invisible force. The deeper one ventures into the mountain, the more powerful and numerous the guardians become, and the temperature drops to levels that can kill unprotected explorers within minutes.
What treasures or secrets Inthikrilix left behind remain unknown. The few expeditions that have penetrated the outer chambers report that the architecture becomes increasingly alien the deeper one goes—as if the mage was building according to geometries that don't quite match the Material Plane.
