The gameworld consists of a number of different terrain types. Some, such as plains, forests and multi-level dungeons, are principally hunting areas. There are also towns where merchant NPCs and storage facilities are available along with villages and fortresses. Other interesting areas include the elven forests where human characters are unwelcome, and a dragon valley. The scaled size of the gameworld is unknown.
Lineage has four classes.
Characters in the Knight and Magician classes are the game's melee and spellcasting specialists respectively. Elves can fight at close quarters and also have some magical abilities, but are perhaps best with bows. Memebers of this class have some combat and spellcasting abilities, but their unique quality is the ability to recruit groups of followers, the bloodpledges of the game's title, that can besiege and occupy castles, an act that reflects the backstory as noted above. Except for Elves, all characters are human. Both genders are available in all classes.
