The legend

One tree. Every story.

In the old tales of the steppe, Bayterek stands at the centre of the world — roots in the deep, crown among the stars, the golden egg of the sun cradled in its branches. Mengüyir grows in its image: one trunk of accounts, tables and tools, branching into every world your fellowship wants to play.

  • Rules that keep their word

    Every roll, modifier and consequence is resolved by a dedicated rules engine for each system — never improvised.

  • A Loremaster that listens

    An AI narrator turns each outcome into living prose, in English or Turkish, without ever touching the dice.

  • One account, every table

    Your fellowship, heroes and campaigns live under a single account, whichever realm you enter.
