Follow the blue line until the next hole.
Keep following the blue line and you'll find a small forest inside the cave. In the red spot, behind the middle tree, there is a hole and inside that hole there is a switch that you must turn right to open the entrance to the Maze of Lost Souls. A sign next to the switch says:
You read: Greetings fellow brother!
Turn the switch to the right and follow the blue sunshine to get to Demona. You know the rest of the way.
Note: if it is already turned right, then turn it left and right again.
Get out the hole and follow this way to get to the entrance of the Maze of Lost Souls:
Now you are inside of the Maze of Lost Souls and it is suggested you follow the next map step by step or you'll face Dragons, Dragon Lords and Giant Spiders. In this path you'll face all the creatures in the list above (Rats ~ Orc Leaders). Keep in mind: don't get out of the path if you can't face dangerous creatures.
Ok, here you are in the final room. There are 2 Dwarf Guards, 2 Minotaur Guards, 2 Stone Golems and 3 Elf Arcanists here. Kill them and take the reward (Griffin Shield, Dwarven Axe and Obsidian Lance) that is inside two piles of bones and a dead body. The final room:
If your level is higher than 60 you can even visit Demona to do Double SD Quest once you are at its gates. Anyhow you'll have to get out of Maze of Lost Souls, so you'll have to follow the path in the next map. Note: there are other ways to get out of Maze of Lost Souls, but this one is the safest and shortest one.
