[Dark Souls] Why are some people like Gwyn, Vendrick, and Lothric so much bigger than you and the friendly NPCs you meet?

Dark Souls goes through different ages kind like alternate universes where different peoples/species rule. A lot of them literally just aren't the same kind of being you are and thus are huge. 

Gwyn and his Kin are gods from a previous age. And you're... A human kinda?
