I should find Nerile Andaren at the Temple in Mournhold and ask her about the recent outbreak of a disease.
Crimson Plague
Nerile Andaren has asked me to deliver a potion of Cure Disease to Geon Auline at his house in Godsreach.
I have delivered the potion to Geon Auline, and should report back to Nerile Andaren.
Upon returning to the Hall of Ministry, I found it over-run with infected rats. They have all been killed.
Nerile Andaren thanked me for helping to get rid of the rats, and asked that I please deliver a potion of Cure Disease to Athelyn Malas in the Temple Courtyard.
I have delivered the potion to Athelyn Malas, and should report back to Nerile Andaren.
Nerile thanked me for delivering the potion to Goval Ralen.
Nerile Andaren has informed me that the rats are coming into the Temple through the basement. While guards have been posted to deal with them, she would like me to look into it. The rats are infected with a disease called the "Crimson Plague", supposedly wiped out during Tamriel's Second Age.
I spoke with a Khajiit named Shunari Eye-Fly. She claims to have information about the disease, but will only give it to me once she has been cured. I must find either a spell or a scroll to cure her disease; I should consult with Nerile Andaren and then meet Shunari in the Temple Gardens of Old Mournhold.
I have cured Shunari Eye-Fly.
Shunari told me the source of the Crimson Plague in Mournhold is Gedna Relvel, a lich entombed underneath the Temple. I have inadvertently caused the spread of the disease by opening her tomb.
Shunari told me of a secret passage within Gedna Relvel's tomb; I must find a rock wall in the bottom chamber and stand in front of it, but I am unsure how to actually open the passage.
I have opened the secret passage in Gedna Relvel's tomb; there was a hidden trigger for it in the floor.
I have killed Gedna Relvel.
Shunari Eye-Fly thanked me for killing Gedna Relvel. I doubt I will see her again.
Nerile Andaren thanked me for killing Gedna Relvel, and stopping the Crimson Plague before it could spread further. She has given me the power to heal once a day in exchange for the help I've given her.
I have killed Nerile Andaren.
