@ GarouxBloodline i will try not to shound condesending or overly critical of what you said but if i do sound it, im sorry.

First of all, Keening could have apeared anywere after Morrowind as it has litterally been hundreds of years since morrowind and since people in the Elder Scrolls dont like keeping things safe for very long it is totally plausable for it to be found by Arniel, alsos, he could use it without Wraithguard because he wasnt tapping in to the heart of Lokan, he was having an experimant with a warpped soul gem so wouldnt actually need it.

The Oghma Infinium is a book, and there for can be coppied (probable only be Hermaeus Mora) and therefore can be found any where Hermaeus Mora deems fit to place a copy.

All mer races come from a single Race know as the Ehlnofey, it is possible to see these genetic forebareing in todays genetic sciences, (so your point in getting a german shephads and pugs and finding wolf blood is actually plausable, as they are both related in some way and come from the same ancestrial origins) so they probably did it in Skyrim by using magic, there science equivilent.

Hope this clears some stuff up :)
