VELORIA
Throne and Grave
“A throne for a day, a grave forever.”
King Aldric is dying and his heir is unknown. In the kingdom of Veloria you are one of 72 people — king, general, priest, assassin, soldier or the farmer nobody notices. Everyone has a hidden loyalty, the world does not wait for you, and how the king dies decides how your story ends.
- 72 characters with secret loyalties
- Play any role, from king to farmer
- Intrigue, survival and a living day–night world
- A different ending every game
The game is not code-signed yet, so Windows may show “Windows protected your PC”: choose “More info” → “Run anyway”.

02 / FEATURES
More than one app.
An ecosystem built for you.
WhatsApp Bridge
Your WhatsApp chats inside Prisma. The bridge runs on our server; messages go into end-to-end encrypted rooms and are neither read nor kept. Details on the security page.
PrismAI
Create and manage your own Meta AI API key and use AI assistance in chats on your terms.
External Wallet Payments
A Monero wallet inside Prisma. It is custodial: the keys are kept encrypted on our server. The risks are spelled out in the wallet notice you accept before using it.
App Library
Apps installed from inside Prisma: Prisma Guide (city and events) and Prisma Photo Roulette (a photo guessing game with friends). Each is installed only after its signature is checked.
04 / HOW IT WORKS
Control in three steps.
01
Download and install
Download the Prisma APK from our website or app library. No app store required.
02
Create an account
Sign up with username, email, and password. Your data stays on your Prisma server, away from third-party analytics.
03
Open bridges and extensions
Connect your WhatsApp bridge, create Session rooms, or open any of the 7 independent apps with a single tap.
05 / SECURITY
Privacy is not a feature,
it is an architectural choice.
We say plainly what we can see and what we cannot. Private chats are end-to-end encrypted; WhatsApp messages are not read, not kept, and exist on the server only encrypted.
- The website does not log visitor IP addresses
- HTTPS and modern security headers
- Two-sided payment confirmation
- End-to-end encryption by default in private chats
- Source code published on GitHub
