"We're going deeper," Jack announced, making the decision. He turned to the surviving miners. "How many levels are there? How far down does this mine go?"
The miners exchanged nervous glances. Finally, one of them spoke up. "Three levels, Soul Warden. We're on the first. The second level has richer deposits, more concentrated Aethrium. But the third level..."
"What about it?"
"No one goes to the third level. Pho forbids it. Says it's too dangerous, that the air down there will kill demons who breathe it too long."
Jack's instincts screamed that this was important. "But there is a third level?"
"Yes. We've seen the entrance. But it's sealed. Pho put barriers on it, magical wards that activate if anyone tries to pass through."
"Show me," Jack commanded.
