Irian, the Eternal Dawn

Irian is the plane of light and hope, the wellspring of positive energy which is the foundation of light, life, and love. The regions of Irian reflect the idea of beginnings and of resurgent life: fertile lands untouched by any tool, glittering crystal forests, and thriving homesteads and communities. Angels dwell in a grand city reflecting the first days of a glorious empire. The sun never sets here.
Positive energy flows into Eberron from Irian, and the denizens of Irian believe that the simple fact of their existence helps the mortals of the Material Plane. The celestials of Irian are also those most likely to respond to planar ally and similar spells.

Irian Manifest Zone Features
d4 Feature
1 The waters of a spring hold curative powers—curing disease, healing wounds, even restoring lost senses.
2 Clusters of radiant crystals sprout from the earth. A spell of 1st level or higher cast within 30 feet of these crystals, if it restores hit points or deals radiant damage, is treated as if it were cast at a level one higher than the spell slot that was expended.
3 A maple tree with translucent, violet-hued bark and shimmering leaves grows in the heart of a swamp. Creatures that live near it age very slowly.
4 Undead within the zone have disadvantage on attack rolls, ability checks, and saving throws.
