Sithis is neither sentient, nor does he have any kind of influence over Nirn, he is the Soul of Padomay (the void), and therefore, he is literally NOTHING. The Night Mother is most likely Mephala, who is just trolling the Dark Brotherhood. You have to remember, that the Dark Brotherhood was once part of the Morag Tong (a dunmeri Assasin guild). The Morag Tong worshipped Mephala, the daedric Prince of Sex, Murder and Plots, but after they began to worship Vivec instead of Mephala, some people didn't want that, they left the Morag Tong and BAM the Dark Brotherhood came to existence. Eventually, Mephala came and thought "Hey how about i just troll these guys who still worship me?", she began to speak through a corpse, calling herself the "Night Mother" and you can imagine the rest.
