I have been playing Taasen a little bit recently, and I recently discovered a variant of the Taasen board that I believe dates back to the heady days of Myrmil! I think it's an alternate board layout created by some engineers of Nakimono Industries in commemoration of the advent of the Trato-Yauronic device. It's design is probably partially based on the device, with the three shards of Chijimutite represented by the traditional green spaces.
The board topology is the same as for regular Taasen, though for beginner players the altered visuals may affect the way one thinks about the game...
