Talk to the man sitting on the floor.
He wants a knife. He opens the door so you can get out. Talk some more about his motives and then use the door to go outside. Walk to the left to find a bridge. Look at the bridge to find DIAMONDS underneath. Use the bridge to find a lake. On the right side of the lake there’s a piece ripped apart. Take the piece of LAKE with you.
Walk south to return to the bridge and go to the left to find a woman ashamed of herself. Talk to her to discover she finds herself ugly. Give her the piece of lake so she can use it as a mirror. You’ll catch her TEARS. Leave the woman on the right and use the bridge again to cross.
Call over the lake to the ferryman and pay him with the diamonds. On the other side, talk to the man who is abusing his wife. Ask him why and give him the tears. Now he doesn’t need his wife anymore. You’ll get his KNIFE. Go south to return to the lake and south again to the bridge. Walk to the right and enter the lighthouse. Give the knife to the man to end it all. Talk to the phoetus to find out if it’s alive…
