I have been warned about traveling through the Mephalan Vales. Apparently there have been sightings of Spider Daedra recently as well as reports of people missing.
Hunting Daedra
The guard captain, Flaalsa Irano, is apparently really concerned about the Spider Daedra sightings in the mountains. She'll most likely be somewhere in the Akamora Guard Tower.
I've spoken with Flaalsa Irano, who is pretty worried about a Spider Daedra colony attacking travelers close to Akamora. She's willing to pay a decent amount of gold to anyone willing to go out and put down the Spider Daedra.
I've agreed to help Flaalsa Irano. I must find and eliminate the Spider Daedra Matriarch. She believes that with the Matriarch gone, it should cause the rest of them to scatter. The guards in Tomaril Manor can probably give me some directions.
I have killed the Spider Daedra Matriarch. I should head back to Akamora and report my success to Flaalsa Irano.
Flaalsa Irano thanked me for taking care of the Spider Daedra Matriarch and paid me the 1000 drakes she had promised.
I have killed a Spider Daedra Matriarch which seemed to be responsible for a number of corpses close to the town of Akamora. I should probably report this to one of the guards there.
Flaalsa Irano was very pleased to hear that I had taken care of the Spider Daedra problem and rewarded me with 1000 drakes.
