As the player explores, he encounters various types of creatures native to the different continents, some of which are able to be recruited. Most of these creatures are significant upgrades from the normal human forces available to the player at the King's castle, and are required to defeat the tougher villain armies. However, as their strength increases, so does the amount of gold required to retain them, which must be paid weekly. Although the player's commission can be raised in a variety of ways, such as maintaining a garrison of forces at a captured castle, if their costs exceed their income for too long, and they run out of money, their army will abandon them. Furthermore, each of the various army units have either a positive, neutral, or negative predisposition towards other. An army composed of creatures that "dislike" each other lowers their "morale", making them much less effective in combat. Conversely, recruiting creatures which share a positive predisposition towards each other increases their morale. Assembling an "ideal" army is another open-ended aspect of the game.
