Starfield - Bethesda's new space IP: will probably be full of fun and easily trackable bugs

Shouldn't they be extinct if this takes place after Skyrim?

not really no, especially since they count the extremely retarded TESO lore as canon.
other than that it's not out of the realm of possibility of akatosh doing a little trolling and the fat neckbeard they keep at bethesda will go through the same angle in order to explain dragons returning.

Skyrim's MC is literally called "the last dragonborn."

not with mods it ain't.
