Due to the lack of heat conductivity of the methane and nitrogen gases that abound on its surface, Anarrenakt is remarkably cold year-round. Acting as a paradox to the frigid surface, a massive rupture in the crust of the planet opens into its depths, where intense pressures of rock cause tremendous heat and friction, causing the rock below to melt and become liquid. This liquid bubbles to the surface through this rift, creating what scientists have affectionately dubbed a "drop of fire on a snowball".
