One may find
Outer domains as well as Underground domains called
Barracks in the Dungeon.
Outer domains can be found both during exploration of the
kingdom and exploration of the
Dungeon and will be seen on both cells.
Barracks can be found only during the exploration of the Dungeon.
To send explorers to the Dungeon, open your
Expeditionary Corps and check
Dungeon next to the coordinates of the cell
Missions cannot be sent from other cities. Underground missions can be sent only from
Pits,
Mines, and
Capitals.
That is why when trying to send a mission to the
Dungeon from an inappropriate estate, you will see a
notification window:
There's a penalty on the duration of all underground missions in the Dungeon: +25%.
Penalty "+25%" can be temporarily canceled with the help of a
Tournament service
