Meesei was quite familiar with the stories and legends of Hermeus Mora, so she knew how dangerous he could be. He tended to attract seekers of knowledge, much like herself. But, while he often did provide said knowledge, those who followed him could become trapped in his realm by their own obsessions. He was not truly a good nor evil Daedra, but Meesei had no doubt that he was only making this offer for his own benefit. At the very least, Meesei did trust that any information the Prince of Knowledge provided stood a good chance of being accurate. 

"I am sure you understand that, under other circumstances, I would have a difficult time trusting you, Hermeus Mora. Daedric Princes do not give charity to mortals. But, lord Hircine told me of your coming, and I trust my lord's judgment. If you are willing to share the location of a stronghold we can make our home, then we will be grateful for the knowledge. However, if there is a price for it, if you are expecting some kind of sacrifice, then I may have to politely decline." Meesei answered. 

Mora gave another, gurgling hum. "Your...motivations are irrelevant to me. You will accept this knowledge. I...know it." Mora's largest eye disappeared, then reappeared on the other side, looking to his Altmer servant. "Give them the...key." He commanded. 

The Altmer stood up from the ground, then walked over to one of his Imperial companions and pulled an object from her bag. Still as calmly as ever, he walked up to Meesei and handed her a strange engraved sphere made from Dwarven metal. Mora had referred to it as a key, though that function would not have been obvious by looking at it. 

"This...attunement sphere will grant you access to the place known as Fal'Zhardum Din, in the land you call...Skyrim." Mora continued. "A place long for-gotten, like the Deep Elves who built it. It is the solution to the...problems you do not know you will have. My followers have a map that will lead you to its entrance. The only...price for this knowledge that I have given you is that you end Clavicus Vile's ambitions. You will defeat him before he becomes more than an...annoyance to me."

A few more of Mora's eyes focused on Meesei, and thought it was hard to tell for sure, it seemed like more of his tentacles were moving closer to her. "I have no more gifts for you, but...there is always more knowledge in my li-brary. You will keep this black book. If you wish to earn this knowledge I possess, then you need only to read it. Apocrypha is a place of great power and secrets, any of which could be yours. But...this is already known to you, Champion of Hircine."
