This book is about the origins of the Warsmith… signed by 'Umbra'.
I met Salty - a genuine skeletal parrot! He was once a man, but was changed when creating cursed cannonballs from one of Flameheart's cannons. His partner in alchemy was the weaponsmith, Wanda, who forced him to take the brunt of the curse. But she did not escape unscathed. Flameheart's hatred fed her own, until she became the twisted skeleton captain, 'The Warsmith'. She waged a failed war on the Outposts.
