Keystone Kingdoms

A medieval MMORPG where every trade is a puzzle.

Fish the lake, fell the forest, smith, sow and build a home — then take your place in a living realm with its own ranks, rents and rivals.

Checking the realm…

The game

Work, build and rise in the kingdom of Aldermere

You arrive in Aldermere, a walled castle town beside a lake, as a nobody. A wizard needs a hand with a cracked keystone, the smith needs ore, the cook needs supper — and every job you take is played as a short puzzle, not a progress bar.

Everything that matters happens on the server: your coins, your land, your rank and every craft you complete. The world keeps turning whether you are there or not.

What you can do today

Already in the alpha

Every trade is a puzzle

Fishing, farming, cooking, fire making, woodcutting, mining, smithing, carpentry and tailoring — each ability opens its own board. Play it well for a better result.

Build anywhere

Snap walls, floors, roofs and doors together, log cabins to stone keeps. Buy a plot or claim open ground, fit locks and cut keys for your friends.

A feudal ladder

Climb from Thrall to Knight and beyond through the realm's officers. Lease land, pay rent and tax, and keep your holdings in good standing.

A world that lives

One-hour days, rain and storms, birds in the treetops, wolves at night. Rivers run to the sea past ruins, camps and three dungeons.

Swords, bows and spells

Strike, shoot and cast from your hotbar, learn new abilities from teachers around the town, and hunt the Greyfang alpha — or gather a party for the dungeons.

A voiced beginning

Magister Orrin's twelve-quest introduction walks you through the town's trades, with fully voiced scenes along the way.
