A good LORE for a Paladin Orc or Argonian

[C2HGaming]

Now I'm going to be making a Paladin build. However I want him to be a bit different most Paladin's are human and such and yeah that sounds great but I wanna be something different.

So I'm trying to pick between an Orc Paladin or a Argonian Paladin. Both have different racial skills which I'm not to worried about but who knows they might come into play for my next question.

If someone can help me on the kind of LORE on why an Orc or Argonian would become a Paladin (both are not really known for magical powers or holy powers.) It doesn't have to be too long of a LORE just something to "jump start" it lol.

If none can help me then if someone would point to a good site that helps for this type of question, really any help would be most kind. :)
