Not gonna lie, searching for 'Dragon Steel' made me wonder if the OP meant 'The Dragon-Steel Book' from Brandon Sanderson's Cosmere, which is often shortened. If that's the case, the key character is unquestionably Hoid. It's more a framing device, a collection of his stories, so he's the narrator and the throughline. But if you mean a different book with a similar title, things get murky.
I spent a good twenty minutes down a rabbit hole trying to find a standalone novel called 'Dragon Steel.' Closest I got was some obscure fantasy from the 80s and a few web serials. Might be a typo for 'Dragonsteel,' which is a material in several series. Sometimes readers blend titles, maybe thinking of 'A Game of Thrones' with its Valyrian steel? Without a confirmed author, pinning down characters is tough.
My advice: check if it's a Sanderson reference. If so, Hoid's your man. If not, maybe give the full title? The fantasy landscape is littered with dragon-this and steel-that, makes proper identification a real chore.
