Session 13

The Astral Plane

Heroes (lvl 6): Bastion, Thrum, Aibell, Percival, Yvaine, Emile

After escaping the destruction of Athas, the heroes find themselves adrift in the Astral Plane alongside Sharnak and the newly rescued Wanderer. Their footing is no ordinary ground, but the immense corpse of a forgotten god, drifting silently through the silver void.

There, Sharnak finally shares part of the truth.

He speaks of a hidden force known as the Triune Concord, a mysterious alliance working to reshape the multiverse itself. Though he does not know the identities of its leaders, he understands their goal: to simplify creation by removing worlds and realities they deem flawed or unnecessary. Athas, he explains, was only the first victim.

Against them stands Velcarion, the Master of Endless Tides. Unable to prevent every world from being targeted, Velcarion instead seeks to preserve what can still be saved. Across the multiverse, certain individuals serve as anchors—living embodiments of a world's identity and history. By rescuing these anchors before their worlds are erased, Velcarion hopes that something of those lost realities might endure. The Wanderer was one such anchor.

With their mission complete, the heroes return to Sigil. For the first time in many weeks, they enjoy a brief period of peace. The days are spent recovering from their ordeal, replenishing supplies, purchasing scrolls and minor magical curiosities, and enjoying the relative comfort of civilization.

Yet Sigil rarely allows tranquility to last.

While traveling near the Foundry, the heroes notice a patrol of Harmonium soldiers approaching. Their formation is deliberate. Their expressions are grim. This is no routine patrol. Something has changed. And whatever business the Harmonium has with the heroes, it is clear that it is not friendly.
