With his choice of wording, one could have assumed that Areldril was trying to confuse them, though he quickly clarified. "Yes, of course Vile cannot be killed in any literal sense, short of somehow bringing him to Aetherius first. No, but a Daedric Prince can be...how to put it...displaced. Their physical form can be destroyed. Like any other Daedra, they will regenerate, and quickly. However, the process of destroying a Daedric Prince drastically diminishes their power. It is a rare event, but it has occurred in history. As you mentioned, Dagon was destroyed by Martin Septim. Molag Bal was once destroyed by a mortal, albeit with the aid of the Chim-et Adabal. Even Vile himself had his power diminished a few hundred years ago by that whole affair with the Umbra sword and that floating city. Clavicus Vile had been in a weakened state for the majority of the Fourth Era, but something happened recently to change that. Well, within the past few decades, before the start of your war. Historically, Vile has always been held in check by his counterpart to prevent him from attempting schemes like this. Are you all aware of the lore surrounding Vile?"

Meesei gave a simple, confident nod. "Clavicus Vile is the Daedra we are all the most familiar with, save Hircine himself." She answered. Naturally, they wanted to be as well-informed of their enemy as possible, so most of the pack was educated about him. 

"Good, then you know about his counterpart, Barbas. The Daedric hound is subservient to Vile, but he has always had the power and will to keep his master from overextending with these sorts of ambitious plans. Vile's actions have been uncharacteristic of him, compared to his actions throughout the rest of history. I can only conclude that something has happened to Barbas to diminish his influence over his master. I cannot say if this is something we could potentially use to our advantage, but it means that he is able to act unhindered" Areldril explained before pausing, then taking a moment to clear his throat. "Ah, but more to the point. You wish to know how to defeat Vile. He is essentially a god, with powers magnitudes beyond anything your entire kind is capable of, combined. You would need the power of a god to challenge him, but fortunately, you have access to a god willing to fight him, yes? Your master Hircine. Of course, Hircine's power has waned in your war, while Vile's has grown. Your master does not have the power to defeat him, but it is possible for even mere mortals like you to bridge that gap. It will be no small task, but you need to secure the kind of power that can affect Vile in that fight. Fortunately for you, I have already done the research for you. As much as I could, at least. The first step will be for you to obtain the blood of a Daedra to serve as the shell for a weapon against him. Specifically the blood of Vile himself. Blood, in this case, referring to his essence. In Tamriel, the only way to find a Daedra's essence is in the form of their artifacts. All Daedric Princes have at least one, and Vile is no different."

Meesei hummed, thinking back on what she knew of Vile. "The most obvious artifact is the Masque of Clavicus Vile. It has been given as a reward to those who serve Vile several times throughout history. There is also the Bittercup, though I would not even begin to know how to find either of those. Not to mention, neither of them are weapons. One is essentially a helmet, and the other a cup."

"What, you expect us to beat a god to death with a cup or somethin'?" Lorag added. 

Areldril actually gave something approaching a chuckle as he responded. "Not quite. You do not necessarily need something sharp and pointy to serve as a weapon against Vile. But, I will agree that something which is already a weapon can be more easily converted to this purpose. Fortunately, those are not his only two relics. There is an axe, named the 'Rueful Axe', which, quite ironically, was given to a man to slay his lycanthrope daughter as a 'cure' for her disease. It is made from Vile's essence, and could be used against him with the right kind of power supporting it."
