Jen, this is an Energy Fountain. I can draw vital energies from it. Vital to your survival.
Energy Fountains are large crystals projecting from a base on the ground. Scree can summon energy from them, energy which Jen can summon from him in turn. Energy Fountains are non-renewing. Each can supply about one full refill of Scree's energy storage. They can be found in each of the Four Realms, as well as the Nexus.
