You read the letter.
I am Elder Bania. We at Ilya are concerned about the impact and pollution western mechanical civilization has brought to the natural world.
I received a letter from DeRodin Village requesting help. The pirates at Bone Reef Peninsula have started to develop machinery as weaponry. This could cause serious pollution.
I can't go there myself, as I'm wrapped up with research, but please go to Boneblade Sea Fortress and take care of the issue.
Are you part of civilization, or are you a force of destruction? We can no longer condone the continuing degradation of the environment. You have the means to put an end to this!
Go investigate Bone Reef Peninsula in the south!
