Progress text
I've come to Undercity because I heard their alchemists have been studying long and hard on how to find a cure for their own illness. It was suggested that perhaps they could help me too. Although this place makes me feel far from welcome, I had no choice--the sickness that found me is tearing me up inside and I needed their help immediately.
Completion text
Chemist Cuely has been very accommodating... disturbingly so. But if he says this will help me, then I have no other choice. I don't have time to find any other solution. I've already spoken to priests and shamans, none of which could help me. Let us hope that the Earthmother watches over my spirit.
