Hi, Maestro. Welcome to MarsDawn.
A bit of background information: Our resident alien species, the Ipsolstai, seem to use almost exclusively visual communication. According to the probes' reported observations, they first attract attention by clicking pincers at the end of clusters of tentacles. Then rapidly changing colors and patterns are displayed on their tegument. The more critical the discussion, the brighter the colors and the more rapid the change.
In addition, we have received transmitted images of strange glyphs carved in stone near the entrance to Jose's cave and also another cave that Andrew explored.
These glyphs may or may not be related to the Ipsolstai occupation. They may be much older. We can only speculate.
Any xeno specialist is welcome here.
