The Telvanni Agents

Eydis Fire-Eye in Balmora, Guild of Fighters will ask you to kill four Telvanni agents responsible for thefts and kidnappings at the Caldera Mine.

If you don't know the way to the Caldera Mine, proceed to the town of Caldera and ask around about Caldera ebony mines; most people will give you directions. Proceed out of town through the west entrance and follow the directions and signs to the Caldera Mining company.

The lookout, whose name is Alveleg, just outside of Ashanammu, will allow you to approach, and will even chat with you a little. However, if you ask him about Telvanni agents, he'll turn hostile and attack. Eliminate him and then enter Ashanammu to take out the remaining three agents, Alynu Aralen, Sathasa Nerothren and Fothyna Herothran. They will attack as soon as they see you, and they are grouped together, so be prepared.
