Gnomish

This language is functional and filled with right angles and dots that allow there to be layers of the text overlain with an almost three-dimensional effect. There is a main narrative, and then context and grammar are written over the top. It is rumored that this language originally was an ancestor of the Mech language, but any proof has been lost thousands of years ago.
Gnomish is included in the Gether Guide to Languages on DrivethruRPG:
