???/Mysterious Island (Inner Sea)

Overview
This location just appears as ??? when Luka enters it. Everybody wonders what is this place. A time worn journal informs the group of the demise of a shipwrecked crew, and several differences appear between the apparent local geography and the one registered by the crew. The journal speaks of a monument with an unsettling inscription and a thick fog, without giving further details.

The other examinable items do not provide further information.

Trivia

 * The BGM playing in the area is dungeon_labo 1 (which is used in the Administrator Tower and the laboratory under Remina in the original storyline), making it safe to assume that the place will be related to the barely touched Alliance of Wisdom.
