So I have been thinking about how seath the scaleless is immortal because of his primordial crystal, and noticed that the dragons could of been double immortal.
The dragons of old, are immortal because of their stone scales. But Seath was born with out any so he found a way to make himself immortal with crystals.
So if Seath didn’t betray the dragons and found the crystal, then could the dragon be double immortal. Since both their scales and the crystal will fuel their immortality and they won’t die unless their scales get pealed and the crystal is broken.
Just some theory for thought really.
