Tetrahedron 4

A Tetrahedron 4 can be found in a pile of rubble on Kethsi. It currently has no known use. However taking it to Marius Giste or Barnabus Hurma in Varok museum spark's the conversation "interesting, but it's of no use to me at the moment, i'm afraid." implying that perhaps soon showing them the rock may be requred to progress through a yet unreleased quest



The name, along with various other piles of rubble seen in Kethsi, suggest there will be more tetrahedrons to be found.
