Algyd, known as the Rancor-slayer, was the youngest son of Queen Alren-hi of Thelisae. Although his father was Patrev, Alren-hi told him his father was King Arhidreth. Algyd gew up idolizing his supposed father, although the man had died before his birth, and listened to stories of the king's bravery and heroism. In 792, Algyd slew his first rancor. In 784 BBY, he married Michari, who bore him a son named Ilo the following year. Four years later, Algyd drove Alabri out of the Thisspias system forever.
