Demo note
The current Steam demo only opens Gran Dragnica and Scarlet Will, and only their first two seasons. See the Demo FAQ before treating this list as the playable demo roster.
Mission Mode Objectives
The official system page says missions can include these objectives. It does not assign each objective to a named nation on that page.
- Unify the Continent
- Strengthen Strongholds
- Collect Designated Items
- Collect Monsters
- Gather Allies
- Repay Debts
- Defend Strongholds
Between seasons you can upgrade strongholds with materials, send unused leaders on Explorations, hire extra leaders and monsters, and buy or sell gear from the Traveling Merchant. Those systems sit on the same official system page as the mode list.
