That was another dead body. But it was strange. That looked like as ancient European knight. Usually, there is a lot of bodies and most of them not speak. So, I mean, that knight spoke.
"Get out here!"
He(she?) said. Then, he suddenly attacked with his huge sword. So that I needed to fight with. It was a kind of the hardest battle ever. Finally, I could defeat him. But he was still alive and said that.
"I'll be back soon..."
Then he left there to somewhere else.
On the other floor, I met a goods seller. He said that he sold some equipment for warriors like me. In this underground world, we treat some fragment of stone called "Magical Stone". I thought they know any information about him, that knight. So that I asked him about that.
"Hey, who is that? Is he something special or...?" I said.
"Ah... you mean that knight? He is a kind of mystery of here..." He said.
And we walked closer to me, then whispered.
"We have a rumor about him... he is an undead."
I was really confused because moving dead body was not so rare in this world, but we don't call it "undead". I didn't know what he meant. I ask him about detail, but he didn't talk about that.
After I started the battle again to others. But in my mind, I was still thinking about him.
