ok so I was wondering if these two games had an impact any at all on the lore? and another question is there more to the storylines then what I find on UESP? one thing I found that might be related is a short passage from the pocket guide to the empire 3rd edition. "More troubling is the recent prison break at the formidable Blackrose Prison. Though it has since been sealed and its weak points mended, some of the worst murderers, thieves, and political revolutionaries had already escaped into the swamps. It is believed unlikely that any of them could have survived the cruel, dangerous lands of inner Black Marsh." could that be related to stormhold? but that doesn't make sense because stormhold is a different city.

edit: just to be clear talking about stormhold and dawnstar the mobile games. and is shadowkey considered canon?

Canon isn't really defined, we don't have a Starwars system with rating system to rate the accuracy and truthfulness of a piece of lore. So unless things are obviously not set in the same Tamriel as everything else, all the games are part of lore.

You can read the story of shadow key http://www.imperial-library.info/tsosk/.

yea I've seen that so what about the storys of dawnstar and stormhold? is there more to their storys then the little that i can find on the internet? or is that all?.

its a cellphone game, what do you expect?

Yeah, you'd get more answers if any of us had played it. I presume the events in those games are at least compatible with the lore, but if it's canon, it is extremely obscure canon.

So I suppose someone could cite those games as evidence for a theory, but almost nobody would know what they were talking about.

I do believe they are canon in the sense that the events DID occur; I don't see any conflicts in those games with previous/present established lore. I think the confusion (at least in Shadowkey's case) comes from the fact that Shadow Magic isn't really mentioned at all outside of Shadowkey, so one would wonder if it still exists in the TES world. To which I would reply that it does, it's just not mentioned or presented in any other games (much like how spears and crossbows still exist in TES series during Oblivion, they're just not presented in-game).

That's my two cents on the matter, anyway.

Yeah, I've yet to see a convincing explanation of the differences between the sharp delineations of the schools of magic and shadow magic, aside from the latter's reliance on slightly more esoteric forms of energy like emotional passion.

Probably it's just a deeper implementation of a subject that is, in most ES games, just glossed over with a really basic system. Like, theoretically, some characters in ES games could be using "shadow magic", but the game system doesn't differentiate between different types of casters. (For another example, Necromancers don't, in-game, have any special game systems to implement anything different about their magics, despite the institutional divide.) Of course, where Shadow Magic is concerned, I speak from ignorance.
