There is a secret area that is HARDER than Abbyson. To get there, get the sacred stone from Vinheim (Mithos' Castle). Then go to Sybak. In the library on one of the shelves near the upper-right-hand corner, there is a book with an exsphere. When the cut-scene is over, go to Heimdall (elf place after torrent forest). Then talk to one of the elves near the windmill. He will talk about the relation between the sacred stone and the book. After that, go back to sybak and go to the book. Origin will give you a breif warning about this place. Heed his warning, this is the hardest place in the game. You WILL lose if you can't think fast and move quick (or stand still). There is something called soulfire that is basically what lets you keep going through the underworld inside of the book. If you stand still, your fine. That's all i will tell you. If you need more help, email me at firstname.lastname@example.org. Have fun
P.S. This place contains all of the monsters from tethe-alla.
P.S.S NO SPAM!
