A studio. Two products. One world.

Your world, ready for
any AI tool or game engine.

Mimir is the structured worldbuilding platform that turns your lore into living data — feeding your AI workflow, your game engine, and your creative process from a single source of truth.

Built by makers,
for makers.

Shieldwall Games is a small independent studio. We build the tools we needed and couldn't find — then we share them. Mimir came from years of worldbuilding work on our own games. Now it's yours too.

Our games come from the same place: things we wanted to make, built with care, sold honestly. No hype. No filler. Just craft.
