ember power cell

A roughly grenade-sized chunk of what looks like glowing stone or glass, the same red-orange as the engines and rifle blasts of Glowing Eyes' fleet. Every hovercraft on this world is powered by one, slotted into a hatched compartment under the deck. Aux guesses twenty or thirty cells might pay for a Skip off this planet; pulled from a ship in flight, the vessel falls. Cooler in the hand than its glow would suggest, and a more stable form of Investiture than the spear-tip embers themselves. STD:TSM:Ch 6
