# Welcome to Sonder

> A dark fantasy town and dungeon game for mobile, where every hero has a mind of their own.

Sonder is a dark fantasy town and dungeon game for your phone. You build a walled town of eleven buildings, you pick who goes in, and you send your heroes to farm, delve dungeons and climb a Tower of twelve floors.

Once the fight starts, they decide. Every hero walks in with a past and nine traits of their own, and those traits choose when they charge, heal, loot or run.

## How a day in Sonder goes

**1. Build the town**

Your town is home. Peasants work the Trades, your heroes rest, train and make friends, and the cemetery is where the fallen come back.

**2. Farm and delve**

Scouts find dungeons that stay open for a few hours. Pick the party and their gear, then send them in.

**3. Watch them choose**

Inside, you do not steer. Each hero reads the fight through their own personality and acts on it.

**4. Loot, craft and climb**

Workshops turn what your heroes bring back into gear. Then you take the strongest party up the Tower.
