Actually if you look at the Lingering Dragoncrest Ring in Dark Souls 2 it has the description "A ring used long, long ago in the land where Drangleic is now" This ring in Dark Souls 1 was "A special ring granted to only the most accomplished sorcerers at Vinheim Dragon School." Which would seem to imply that Drangleic was not Lordran, but Vinheim instead. Plus they had their own dragon school.cgentero said:Your whole theory is based on the idea that Drangleic isn't Lordran, which IMO is disproven by dialogue with Straid.
Also Straid is a powerful sorcerer and in Dark Souls 1 Vinheim was definitely a land known for it's sorcery.
