When he arrived, he saw only a strange artifact sitting there. It looked like a vertical cylinder covered in markings with a pair of serpents snaking up the sides. They met to hold a dodecahedron in their mouths. Each side had a lock, all unlocked except for one. Beside it lay the dead body of what had obviously been the life sign. It looked like a Vulcan, but the facial features were all wrong. It had jabbed an obsidian key into it's forehead as soon as it began to materialize. It lay on what used to be a spacesuit but had been ripped up by something. Ender removed the key with shaking hands, and then he looked at the artifact. "I wonder..." he said to himself, and stuck the bloody key into the final lock. Then, with a decisive twist, it unlocked.
