Game of Thrones dragons

Of the 25 dragons in the catalogue, only ONE is established.

And it is Grey Ghost, the one we know least about: wild, riderless, with no birth year. Since the source claims almost nothing about it, there is nothing we had to infer. More is told of the other twenty-four, and that is why each has something inferred or disputed.
