Danny glared at the stairs as he realized he had come full circle. Stuff like this was supposed to be a ghost's priority, but he hadn't done it. Sighing, he logged it under a side-effect of the portal.

"Maybe there's an easier way to get up," Danny sighed and moved back to the first floor.

Wandering further down the main corridor, Danny only found more offices. That was, until he found an old, steel cage elevator. He would have not even considered trying it, but the lights were still on. It seemed there was a power source still active in the old place.

Stepping in, Danny closed the cage door…then thought better of it. Elevators were never a good idea. Getting out, he continued down the main hall. Suddenly he realized how tired he was from being on his feet all day. He slipped off one of his shoes and began to rub his foot, leaning against the wall.

The wall he was leaning on gave way, though, and flipped him into a space behind the wall. Danny checked himself over to make sure that he hadn't gone intangible. Nope. He was all there.

So…secret passageways?

Danny rolled his eyes, this was getting cliché.

He flipped the flashlight back on and looked down the small hallway. The walls were undecorated and the floor, unfinished. Walking back the way he came, Danny noticed that about ten feet back, there was a ladder leading down a kind of tunnel. Danny grew curious and decided to explore a more downward direction than previously.

Danny started the climb. After five full minutes of climbing, it was obvious that he was already below the basement. Five more minutes later, Danny hit the bottom of the shaft.

Danny decided that his flashlight just wasn't working and slid it into his pocket. Holding out his hand, a ball of ectoplasm appeared, glowing brightly. What he saw was curious, to say the least. The surroundings were best described as catacombs. He was currently in a large stone tunnel. Obviously it was very old. Probably revolutionary war era.

Deciding to only go a little further, Danny stopped when he found a heavy, iron door set slightly into the wall.

Danny shrugged and turned the ancient knob.

The ball of ectoplasm lit up what Danny would most likely consider the most amazing thing he had ever seen. Taking out the talkie, Danny said, "You guys need to get to the front of the main hall now, you're not going to believe this." Danny quickly steered his way out of the room, grabbing one small memento and starting to move back to the shaft. Then he tripped over something. It was a very thick set of wires.

Danny immediately thought of the power source that Tucker had mentioned. He followed them to another door, which he warily opened. The sight that met his eyes was at once more horrible and more amazing than his former discovery.

"Holy Mary Mother of God," Danny breathed.

"Aren't you all back a little early?" Blake asked, concerned that something had happened. Everyone except for Danny had come walking down the hallway.

"Where's…Danny?" Jeremy asked after a moment.

A knocking on the door revealed exactly where Danny was when the oak door opened.

"Danny, wait. How did?" Jazz stuttered.

"Weren't you on the second floor?" Sam asked in confusion.

"Catacombs," Danny answered.

"You're kidding," Tucker said. The computer he could believe. This was just too weird.

Danny let loose a small chuckle. "That is probably the least surprising thing I found. Tucker, can I barrow your P.D.A?"

Tucker handed it over.

"What's up?" Blake asked, concerned.

"Well, I think I might have found the generator that looks to be powering Tucker's computer and the elevator, I just can't believe it." Danny explained.

"You found an ancient system of tunnels below a hundred year old museum. What could be that hard to believe?" Jeremy deadpanned.

"Here it is," Danny exclaimed. "During the early sixties, two prototype miniature Nuclear power plants were created. One was decommissioned. The other disappeared. Until now. About a hundred feet down, there is a nuclear generator."

Jaws dropped, but Danny wasn't finished.

"And in another room, I found this, and a few hundred more bars," Danny informed them and handed over small bar of metal.

"No fucking way," Jeremy breathed as he saw the bar. It wasn't so much that what he was looking at was gold, it was the small insignia that marked where it had originated.

Emblazoned on a small bar of pure gold was the symbol of a fallen superpower.

A swastika.

Nazi gold.
