Azani Blackheart is a Redguard nightblade staying at the Ayleid ruin Atatar. He is a scholar of the Ayleids and possesses an impressive collection of rare books on the subject.
He is also one of the toughest warriors in all of Cyrodill (twenty five levels above the player) and the Fighter’s Guild lost fifteen good men to him as they tried to take his sword Sinweaver from him causing Modryn Oreyn to suspect the Blackwood Company was involved after they managed to retrieve it unscathed.
"That mission was the start of it. That was when Vitellus was killed. We were contracted by a wizard, Argoth, to recover an artifact from Blackheart. I went in there with twenty men. I left with five. Vitellus wasn't one of them." -Modryn Oreyn
"Nothing! I knew it! Azani Blackheart isn't here, alive or dead. The bastards! There was no battle. Azani must have made a deal with the Blackwood Company. My guess is that they paid him off. They get the weapon for Argoth, collect the payment, and tell Azani where the mage is. Easy for Blackheart to retrieve the weapon and collect on it." -Modryn Oreyn
"We find Blackheart and get that weapon. We'll finish this contract and let all of Cyrodiil know what happened here. Blackheart has a fascination with these Ayleid ruins. There's one northeast of here, Atatar. My bet is that he moved his base there." -Modryn Oreyn
