source of power

Exploration Stage: Full Moon Tower
From: Carlos Light
Description: If this werewolf was a great scientist, I would love to talk to him. I have many questions about this device he invented to induce a state of suspended animation. This device seems to require high voltage, but I can't seem to find the power source for it. Would you be willing to search for it with me?
Completed: I have never seen such a perfectly constructed stand-alone generator before! It is made of crystals very similar to those used in anti-fog lamps, and it seems to be making an enormous amount of energy. The problem is that this generator must be shut down in order to awaken the werewolf.
