Layton opened his shut eyes to find himself alone on a beautiful tropical island, scanning around with his senses Layton found the island was deathly quiet there were no other lifeforms present except for him and plants and if he looked further away from the island towards the sea he found the sea clear no fishes no microorganisms of any kind, he had the feeling he was the only person in the world right now.
Layton was perplexed as to his current surroundings according to Minerva he should have woken up from the nightmare and before falling unconscious he was pretty sure he had already won the holy grail war.
Although he was not sure what would happen when he won but it never crossed his mind he would end up on such a weird island if anything he expected to be somewhere close to the root after all that was the whole core of the war wasn't it.
