Ethereal Est is a mystical world closed off from the outside world.
The labyrinth within is said to change every time you enter it.
The weapons you can find in this dungeon are said to have special effects but are unusable until appraised. Beware of the powerful boss monsters that also lurk within.
You can only bring a limited amount of weapons back from this dungeon. You must make the hard decision of how far to explore each labyrinth and what to take back.
