Claimed Path

Claimed Path is a type of passable terrain that belongs to the player, and is marked by four flagstones with a dot of the player's color in the middle (If it belongs to another faction, it is known as "Enemy Path".). It is the only terrain on which the player can build a room (except Bridges, which are built on lava or water), a trap, or a door. On most maps, the player starts out with a certain number of these tiles already claimed, but any more must be gained by having one's Imps claim a tile of dirt path that is adjacent to an existing tile of claimed path or room belonging to the player.
If an enemy Keeper's territory runs into the player's, enemy Imps can turn the player's claimed path back into dirt path, and then claim it for their master. However, this cannot be done in possession, though it is possible in KeeperFX 0.4.9. The player's Imps can claim it back if they are able to work in safety, and when an enemy Keeper is defeated, all the claimed path belonging to them reverts to dirt path.
==Dungeon Keeper==
In Dungeon Keeper, there are four styles of claimed path:

File:Claimed Path 2 Dungeon Keeper.png
File:Claimed Path 3 Dungeon Keeper.png

KeeperFX has more. Path style is determined by the level's tileset.
==Dungeon Keeper 2==
In Dungeon Keeper 2, another benefit of claimed path tiles is that each one generates 1 mana per turn for the player, up to a maximum of 500 Mana per turn.
