Mosaic Mimir

An ancient artifact tied to your fates

What You Know

The Mosaic Mimir is an ancient artifact that R04M—a rogue modron and your unexpected ally—entrusted to you in the Outlands. It’s a databank, a repository of planar knowledge that was part of the modron hivemind’s collective memory. When R04M escaped from Tyrant’s Spiral, it snatched this mimir to prevent corrupted data from spreading across the planes.

Here’s the problem: the modrons in Tyrant’s Spiral have skewed beliefs—twisted perceptions of law, chaos, good, and evil—and if that corrupted data makes it back to Mechanus, it could ripple out across the entire multiverse. The Mosaic Mimir needs to be recalibrated with accurate information from the gate towns to replace the corrupted data.

R04M warned you that the data needs to be balanced and accurate. If it’s skewed too far toward good, evil, law, or chaos, the mimir could still cause planar instability when it’s returned to the modron collective. This isn’t just about fixing bad data—it’s about making a choice that will shape the planes going forward.

You’ve been traveling to gate towns in the Outlands to recalibrate the mimir:

Faunel (Gate to the Beastlands): You calibrated the mimir here after helping the town navigate a crisis with the Vile Hunt. The mimir noted that Faunel had changed—it was slightly inaccurate compared to the old data, reflecting the town’s rebirth after merging with the Beastlands. The alignment read as fairly neutral with a touch of chaos and wilderness.

Sylvania (Gate to Arborea): You recalibrated the mimir here after helping calm Kopoha, a newly ascended empyrean, and defeating a fiendish warband that crashed the town’s eternal celebration. The mimir’s summary would reflect the town’s chaotic good nature and the party’s heroic intervention.

Each calibration is a choice. The mimir is recording not just facts, but the truth as you experience it. And when the modrons process that truth, it will shape how they see the multiverse—and how the planes themselves respond.

The weight of that responsibility isn’t lost on you. Or at least, it shouldn’t be.
