Furius Acilius is an Imperial in The Elder Scrolls III: Morrowind who lives in Ebonheart. He is a deserter from the Imperial Legion who made off with the Lord's Mail by way of a secret tunnel into Castle Ebonheart. He is immediately hostile to the Nerevarine.
The following items are included in Furius Acillius' inventory:
The Nerevarine must find and vanquish the former legionnaire to take back the divine cuirass before advancing to the rank of "Knight of the Garland".
The Nerevarine will likely encounter Furius if they infiltrated Ebonheart Castle by way of the hidden entrance in order to steal Elvul's Black Blindfold.
