If I find anything interesting I'll be sure to hoard it until I release a build. 

The Bloodclaw doesn't worship Boethiah, it goes against Sithis worship since the Morag Tong and Dark Brotherhood are enemies

Again. I said you could refuse the quest but still gain the daggers. They have the same dmg and can be tempered but lower weight meaning less cost to power attack translating to more stamina to zip around with stealth rolls and stealth leaps.

That's not exactly how it works, plus, again, doesn't worship Boethiah.

Also, I said since the Morag Tong. Not by the Morag Tong. Currently they worship Vivec, Almalexia, and Sotha Sil. This was in exchange for amnesty after the murder of Potentate Versidue-Shaie. The DB are actually a splinter cell of the Morag Tong that rejected the terms of the Tribunal. They still worship Sithis, Azura, Boethiah, and Mephala. The DB started the shadow war as revenge for their former comrades forgoing the ancient deities.

That's not true. It is SUSPECTED that is their origin, however another suggests that it was the Thieves Guild they split from. The Dark Brotherhood only follow Sithis. The Morag Tong worships Mephala and Sithis, unlike the Dark Brotherhood.

Yet if you take a look into TES3 and join the Morag Tong they admit this. It's also why you can present writs and brutally murder a mark in front of witnesses and guards without any repercussion.

Again, they would say this origin as they would want to bad mouth the Dark Brotherhood. However, in other sources, it is stated the Dark Brotherhood cames from thieves who murdered their marks.

And they're are theories (which I do believe this one) that the Night Mother is Mephala. For this reason being as a mortal Night Mother being ascended as an unspoken deity is unlikely given that Talos has no power after he died as a mortal. Another theory is that the Night Mother is a tank since the Morag Tong that was kept as an insult, which is debunked by Skyrim. Given that Astrid knows and Cicero knows they are the last sanctuary and she is the highest female member she would be named Night Mother under this premise by Cicero if only out of respect. And as for the theory of the Night Mother being a former Thieves Guild member, the Morag Tong admits the Tribunal agreement and the group splitting due to it therefore destroying the likelyhood of said theory as again, even if she did group up Morag Tong dissidents, it doesn't explain how she could have power after death. And obviously as there is a Listener the Night Mother must have some otherworldly power.
