Prisoner

The Prisoner is a campaign exclusive unit that makes its only appearance in the Welcome Back mission of the Fall of the Trident campaign.

Appearance
Villagers gather resources and build buildings when they are not held captive.

After defeating Gargarensis' and the Giants' forces in the Norselands, right after Thor sealed the third Hades Gate to Tartarus, the heroes and many escorting forces return to Atlantis. Amanra asks how far are they from Atlantis and Arkantos responds that they should reach Atlantis before the dusk.

Immediately, he commands for the head of Gargarensis to be brought before him, and lashed to the ship's bow. As soon as the head is revealed, ravens burst from it and Loki laughs at the heroes, to reveal Kemsyt's head instead; the heroes have been tricked and soon, they view Atlantis on the distance, under attack.

There, the island is being occupied by Gargarensis' forces, and the Atlantean people have been imprisoned.

In-game role
As soon as they manage to establish a base on the beaches of Atlantis, the player must save at least 15 Atlantean Prisoners in order to beat the mission. Then, they must be transported to an islet close to the player's starting position. In order to free them, the player must destroy certain enemy structures; then the Jail Walls will automatically collapse, and the Prisoners will come under the player's control.

Trivia

 * Judging from both the in-game help description and the food cost, it is possible that the Prisoner was originally intended to play an important in-game role, with him probably representing a slave.
 * Prisoners are the only campaign exclusive unit to completely lack an history section.
