The LDB is a Shezarrine. Shezarrine bring change into the world, Lorkhan brought change into the Aurbis (therefore, Shezarrine and Lorkhan are padomaic).

For example, Pelinal is a somewhat-Shezarrine (even though that's a complex matter to discuss). It's mentioned that Pelinal conquered a lot of kingdoms in his time on Tamriel, but he left all of those and went wandering again. Also, Cyrodiil was under the rule of the Ayleidian Empire before Pelinal, Alessia and Morihaus stepped in and brought change (also, if you think about it, the Ayleidian Empire and Umaril might represent stasis/Auriel while Pelinal, Alessia, Morihaus and their rebellion represent the ever changing Lorkhan).

Now what does that have to do with the LDB?

LDB brings TONS of change into Skyrim. For example, the Empire and the Stormcloaks are at a stalemate. But as soon as the LDB joins one side, it changes and that specific side wins.

The most important trait of a Shezarrine is that a Shezarrine always brings change into Tamriel. LDB did, and since he's even named Ysmir by the Greybeards (a title given to all Shezarrine), it's obvious that the LDB must be a Shezarrine too.
