Super rare in-game currency used to redeem for Hypercubes. Can be purchased from the Crystal Special Supply.
A type of heterochromatic crystal inside Hypercube veins. Its scarlet patterns flow and ebb like living, growing organisms. Scholars suspect that Hypercube veins are born from these ultra-radiant crystals, hence naming them Ultracubes.
Ultracubes are yet to be mentioned in the game's story. It is not clear whether they exist diegetically, or purely as a game construct to be used as currency.
