The Aanca always moves to an alternate color square. Its movement diagram contains the destination squares of Wazir, Knight and Zebra. My Spotted Gryphon thread here breaks the movement diagram of the Gryphon into a colorbound piece and a color alternating piece.
Gary, I have EDITED yesterday's comment to your Gryphon Aanca Chess page, adding a reference to a Dai Shogi piece that (partially) includes the Grand Rook.
