Enochian chess was traditionally played on one of four specially constructed boards. Each board represented one of the classical elements. {Earth,Fire,Water,Air} ……….The diagaram above is Fire of Fire & Earth

In all eight initial arrangements each throne square is occupied by two pieces, a king and another piece (in the above case a knight). This double occupancy is only allowed at the beginning of the game. Once either the king or the other piece moves off of the throne square then for the remainder of the game only one piece may sit on that particular throne square at any one time. Both pieces are captured if an enemy piece moves into a throne square while it is still occupied by the both original pieces.
