Back in the time of Bork the Bold, the legendary hero Thordis Skallagrimsdottir famously tamed Sappheral and became one of history's first Dragon Riders.
Framed for her lover's death by a jealous rival, Thordis was banished to the Isle of Doom; a punishment that was meant to be a death sentence as it was known that Deathgrippers lived there.
After three desperate weeks of hiding from these dangerous predators, Thordis discovered the injured Sappheral, whose wing had been crippled in a battle with another dragon. His wounds were festering and he was close to death, but Thordis nursed him back to health with her knowledge of healing herbs.
