The flame essence was sufficient for the forge process, as the substance was producing temperatures the Hollow Avatar's framework recognised as appropriate for the work, as it was the kind of heat that operated on essence rather than on iron and steel.
I lowered the sphere onto the cube and the crystal simultaneously, and the three materials touched.
The cube was the first to begin its transformation under the heat as its geometric structure began to unfold, the precise angles softening, and the cube's surface losing its definition as the geometric binding loosened under the flame essence's heat.
It was designed to be rigid only at standard temperatures, and the flame essence's temperature was above the cube's structural rigidity threshold. The geometric core began to flow, taking the shape of whatever surface it was in contact with, and that surface was the crystal.
