HOLLOW THRESHOLD 1: THE TEMPEST GATE#

Plane Connection: Material Plane ↔ Elemental Plane of Air

ARENA LAYOUT#

A 50-foot diameter circular platform of black stone floats in howling winds. Lightning crackles between three towering storm-spires (20ft tall, 5ft wide) arranged in a triangle around the center. The Tempest Egg hovers 10 feet above the platform’s center, wreathed in electrical energy. A shimmering portal to the Material Plane sits at the platform’s edge (south), while violent winds from the Air Plane tear through an unstable rift (north).

Elevation: Platform (ground level), Storm-spires (20ft), Tempest Egg (10ft above center)
