The Hall of Heroes

"It is not just a tale." the wise woman said calmly. "The Hall of Heroes exists. It is a tomb built by our ancestors that houses the remains of long dead heroes native to this mountain country. And through a certain ritual, those heroes can be called up from their eternal sleep to come to our aid once more if we ever need them again.
"But the tomb lies high in the mountains, so the travel will be dangerous and besides, the heroes will not listen to just anyone, so the stories say. That is why I spent the whole afternoon speaking to the spirits and casting bones. They told me which people to choose for this journey."
