Also the old knights resemble the sentinels in tht they r giant guardians of tht pkace... but wat of their armour and weapons? the boss? and such. then again, you could say that these knights are different looking bcos we aren't in anor londo, so theyd hav to change armour to suit their new place and the dragonrider is possibly the "new" guardian of tht area, like O and S were guardians of the anor londo area

I say the theory is plausible.
