Walking on top of the rainbow was just as strange as it sounded. Something that should have been nothing but an illusion created by the refraction of light but was solid instead gave off a strange feeling of uneasiness. Uriel tried and failed to understand the nature of the colorful bridge and he wished he had an engineer on his party that could share an explanation to some of the strange phenomenons that came to happen during their exploration. However, he was aware of the fact that their current knowledge in physics didn't apply to dungeons and it led him to the conclusion that it wasn't for nothing that the ancient people had far better technology.
"Uhm, Uriel, what else can we expect?" Luna broke the silence.
"This rainbow bridges are supposedly the way humans followed on their way to escape from the first world, but after death their souls return through this very path and we may see some ghosts."
