Aiding Isin Dule
Isin Dule tells you, "Something strange has happened to Tou-Tou. It has been blocked off by some sort of energy. I feel this will result in awful things. A dark portal has been spotted at the entrance to the town. Investigate this and return to me with what you discover."

Mi Chi the Barkeep says, "The pain... the darkness..." Jeweler Lo Dai-Ou says, "I do not want to become one of those monsters. That is a fate worse than death." Rou Beh stares off into the darkness with a vacant look in his eyes.

You have killed 1 Rou Beh the Bowyers! You must kill 5 to complete your task.

You have killed 10 Void Lords! Your task is complete!

Isin Dule tells you, "Those souls are better off having not been fully corrupted by the darkness. I only wish we could have acted sooner to prevent this."

Completing Black Ferah's task Black Ferah tells you, "Isin Dule's forces left with their tails between their legs." Black Ferah tells you, "Ler Rhan will be pleased, the last phase of the plan is almost ready..." You've earned 370,999,979 experience. You've earned 31,799 Luminance. You have been awarded the title of "Soul Siphon". Black Ferah gives you Fortified Mana Forge Key.

Speaking to Isin Dule after helping Black Ferah Isin Dule tells you, "I think you have failed me for the last time. You are a fool who has no idea what you are helping to cause." Isin Dule tells you, "Be gone from this place. May your decisions haunt you for eternity."
