"You sound quite unenthusiastic, which I find problematic in a student, but I'll overlook it for today," Rith purred. "Now. Hmm… Show me your Three-Dimensional Coordinate System. Make it as big as this room."
Evin complied. He absorbed some Therae energies and after a minute, some grids dividing the room into equal cubes appeared in his vision. They were all of the same size, and using them, Evin could calculate the room's length, height and width.
