Rizon: *sighs and lowers his head* Fine… its a shard of materia that I took from the arsenal some time ago. I carefully broke it and influenced the magic inside of the shard to teleport instead of whatever the heck it did before.. I couldn’t tell properly. In any case… *whimpers slightly* The positive and negative charges in the grenade have been swapped and soldered back into the device, thus creating negative energy from the plasma pulse inside. When the energy is released, it activates the Materia to teleport… essentially teleporting anything in the negative-energy blast radius. *frowns* It will tear literal chunks out of anything and teleport them elsewhere.
