A World That Doesn't Wait for the Players.

Most tools are static notebooks. They only change when you type in them. Quartermaster is an active simulation. When time passes, the world reacts. Festivals draw near. Bounties expire. Shops rotate their inventory.

Your players aren't just exploring a map; they are living in a timeline.

The Living World

"A World That Doesn't Wait."

Time is active. When you travel for a week, the calendar advances. Holidays arrive, seasons change, and limited-time job board requests expire if ignored. The world simulates itself in the background.

  • Events & Holidays: The app notifies you when the Festival of the Moon is approaching.
  • Dynamic Economy: That Ring of Protection might be gone if the party waits too long.
  • Active Job Boards: Quests expire, and others might take the job.

The Quartermaster’s Ledger

"We Count the Beans (and the Bricks)."

Whether it's the rations in your backpack or the staff wages for your Stronghold, we handle the math. Track encumbrance, resource depletion, and recurring costs automatically.

  • Survival Logistics: Track supply depletion and coin weight automatically.
  • Stronghold Management: Manage upgrades, staff wages, and maintenance costs.
  • The Treasury: Centralized tracking of liquid assets, gems, and bank letters.

The Improvisation Engine

"Instant Context."

Players entered a town you didn't prep? Generate a local tavern, a blacksmith with a grudge, and a general store with region-specific pricing in one click.

  • Instant Generation: Create NPCs, shops, and locations on the fly.
  • Context Log: Every generated item and transaction is saved to the session log.

The "Why"

For the New GM:

"Context without Complexity."

You don't need to configure a server or learn a scripting language. Just open the ledger and start logging.

For the Veteran:

"Deep Simulation."

Use our economy settings to adjust inflation, regional availability, and calendar drift. Or simply use the defaults and let the engine run itself.
