×This closed yellow door is mysterious to all who encounter it, since no way can be found to pass it in Dugan's Dungeon except in L10, 3N. Because of this, this mystery cannot be solved by Beethro at this current time, and you'll just have to ignore it and continue downwards.
Apologies for the cryptic sort of style I adopted - it's just not to reveal any secrets now for you, so you can enjoy them later.
