Squagg was found by a family of nomads and taken in as one of their own. Despite their show of mercy towards him, he was destined for great evil, and no amount of love or kindness would ever change that. As he grew, his many claws grew strong, and his body grew more and more deformed with each passing year, yet the nomads loved him all the more for his unique beauty and strength in the face of adversity.
On the eve of his 13th birthday, he became overwhelmed by an insatiable hunger. One by one, he hunted his mother, his father, his brothers, his sisters, and even the family elders. When he had finished consuming his entire adoptive family, he scuttled off in search of more feasts.
Among the Shepherds of Rot, it is unclear whether he is shepherd or beast, but perhaps he dwells somewhere in between. He seldom speaks, and roams far afield when camp is set, preferring to sleep in holes in the ground. But none question his dedication to the Grandfather Nurgle, for he wears his blessings more proudly than most.
