The Green Knight is not placed on the board during deployment. In the Remaining Moves phase of any Bretonnian Movement phase, the Bretonnian player may attempt to awaken the Green Knight. Roll a dice – he will awaken on the dice roll of a 3 or more. If he does not awaken that turn, then the player may try again the following turn, and so on.
When the Green Knight is awoken, he may be placed within any 'natural' terrain piece on the table that is difficult ground or very difficult ground (including fo1·ests, rivers, marshes, rocky outcrops but not constructed things like buildings, etc). What is 'natural' terrain should be decided before the game starts, and at least one suitable piece should be placed on the table. The Green Knight may move normally on the turn he appears.
During the game, the Green Knight may disappear at will and reappear in another location completely. If the Green Knight is within (or moves into) a 'natural' piece of scenery during the Remaining Moves phase, then he may instantly be removed from the table and replaced anywhere on the table within another 'natural' piece of terrain, facing in any direction. He may not move any further that turn. Note that he still may not end his move within impassable terrain.
