About Thavernia

Thavernia is a role-playing platform: you create a hero, start a campaign, and an AI Game Master runs it turn by turn. It describes the scene, speaks for the non-player characters, sets a difficulty for what you try, and writes the result of the dice into the world.

Everything runs in the browser; there is nothing to install. You can play alone or with friends at the same table, and in solo play AI companions join the party with their own hit points, levels and opinions. Character portraits and scene art are generated inside the game, and the narration can be read aloud.

The language of the story is chosen when a campaign is created and is separate from the interface language, so the menus can stay in English while the story runs in Turkish. The narration is written directly in the chosen language rather than translated from another one.

Thavernia is operated by Loopcode Bilişim Yazılım Mühendislik Eğitim ve Danışmanlık A.Ş., a company registered in Turkey. The service is governed by Turkish law; the full conditions are set out on the Terms of Service and Privacy Policy pages.

The game has been live and paid since 2026. Three turns are free without an account at /trial; after that it requires a monthly subscription — 720 TRY in Turkey and 14.99 USD elsewhere — which can be cancelled at any time, with access continuing to the end of the paid period.

Turkey is the product's primary market and Turkish its primary language; the other five languages are the same full game.

The sentence the whole design rests on: the AI narrates, the server decides the outcome. Narration is the language model's job; adjudication belongs to a rules layer outside it.

The model does not roll the dice. When the Game Master calls for an ability check it states the difficulty first; the server generates the number, and you throw the d20 on screen yourself. The model only learns the result once it is fixed, and then interprets it. At a multiplayer table everyone sees the throw, who made it and what it came up as, live.

The state of the world — hit points, inventory, gold, levels, quests and non-player characters — is kept in a database rather than in the conversation. The model cannot overwrite that ledger at will: a death the numbers do not support is rejected, large enemies cannot be dropped in one blow, and ability modifiers are capped. After each turn a second pass finds anything that happened in the story but was never recorded and adds it; that pass can only add, never delete.

Thavernia is not connected to the similarly named game Tavernia; they are separate products from separate companies. Thavernia is published only at thavernia.com.

The company can be reached through the site: questions about accounts, subscriptions and anything else go to info@loopcode.co, the address published on the Terms of Service and Privacy Policy pages.

The guides at /guide explain how playing with an AI Game Master works in practice. Trying it takes no account: the three free turns at /trial exist so you can see the whole loop once — intent, difficulty, dice, outcome — with your own hands.
