Forgot to Mention the Crystal Skulls

You find yourself high on a ledge outside the castle, peeking in through a window that was thoughtfully left open. Just below you is a narrow walkway of sorts, ringing the upper level of a much larger room. Through the railing of the walkway you can see below, where a mix of armed men in uniforms and labcoat-wearing scientists are rearranging large boxes and talking to each other in German.

"Nazis," you mutter. "I hate these guys."

"Nein, ve are nicht nazis," says a greying man with a German accent, who is standing just a few feet away from you on the walkway. Funny you didn't notice him until just now. "Ve are merely scientists."

"Mad scientists?" you say. "I hate those guys, too. I had enough trouble with their dinosaur armies back in town."

"Nein, nein, nicht mad scientists, either. Merely, how do you say, researchers of chemistry und alchemism. Alchemists, that is all ve are."

"But you're using kidnapped children as slave labor down in the mines, right?"

"Oh, nein. Ve haff built our own environmentally friendly machinery for the mining."

Do you ...

Say, "Okay, look, I know you're up to no good, so we're gonna fight, no matter what."

Climb down

You Can't Go Back

You decide you've had enough of that nonsense, and decide to head back down. Unfortunately, it was a pretty steep and complicated climbing route you took to get up there in the first place, and you end up on some completely different path on the way back down. This leads you past a small herb garden just outside the castle. There's a fountain in the middle that has some glittering, golden liquid bubbling through it. You scrounge up the only empty container you can find and grab yourself a scoop of the liquid.
