Lakas Mana ("Coffin")
Artwork by
Standard power generator used by the Imperium, "coffins" have the appearance of a 2 meter long chrome pharmaceutical capsule. Like the Gateways and donuts, coffins are artifacts left by the Masters. Although the Imperium can create them with template replicators, they do not know how or why they work.

It is unknown how much energy a single coffin can provide. They automatically provide interfacing points for power cables and adjust their output to the device or devices they are connected to.
