to enemy sieges. The player can also explore different ruins which dot the map, which can yield great numbers of experience points, magical items which can be used by hero units (discussed below), additional resources, or additional combat units. Depending on the surrounding buildings a player's capital city has, quests may become available which consist of the player clearing out four random ruins on the map as steps towards a great reward. These can help increase the power of a player's army. Races and units There are ten different races in the game: Knights, Empire, Elves, Dark Elves, Dwarves, Dragons, Undead, Demons, Orcs and Ogres. Each of these races has six types of units, each of which has a counterpart with the other races. These unit categories could be classed as: Infantry, Archer, Cavalry, Siege, Creature, and Hero, in order of how many turns it takes to produce them. Infantry are typically the cheap, weak units. Archer units can fire projectiles, and are best used as backup for other units, as they can still fire arrows as support even when they are not the active units. Cavalry units are mounted riders who have a good range of movement out of battle, and are more powerful than infantry in battle. Siege units are most useful when attacking a city; they can stay in the "back row" (i.e. not active units) and fire projectiles at a city's walls in order to destroy them and prevent them from firing arrows at the active unit. Creature units are generally large and/or powerful fantasy creatures which are more powerful than cavalry units; they are also often flying units, which have the best range of movement on the map. Hero units are powerful units which can make use of magic items found in ruins to increase their skills. They also have a special "leadership" ability which can increase the power of other units. These categories are loose, however. While all units correspond to each other, some races have units in these slots which deviate from these categories. Units can gain experience points, and thus can gain levels, making them more powerful and allowing them to increase their special abilities. However, even a very powerful unit can be defeated by weaker units. Each of the units has the characteristics of its race. For example, the nature-oriented elves have treants, unicorns and elven warriors as units, while the
