Martian (High Weir)

Martians are an ancient species who once built an enormous city on the High Weir plateau on Mars. Nowadays, only the city's temple remains.

Judging by their carvings, the Martians had high foreheads, big beady eyes and almost no chin.

They had no writing system, but instead had means to record holographic images inside crystals.
