I know this post is old, but I just want to confirm with everyone that it's a [b]basilisk[/b], which is a type of [i]dragon[/i].
The reason I know this is because, when you apply the Basilisk's Glory ornament to Suros Regime, the exact same creature found on the Suros Fire emblem appears on the side of the weapon.
Also, for the record, I believed it was a dragon long before finding out what it actually was. (That was the reason I began wearing Suros Fire instead of the Born of Fire emblem. LOL)
