As younglings, Orrin and his brothers Linx and Raal may have bitten off more then they could chew when they left home with no real plan on where to go. They wondered for some time following the rivers until they found themselves in the Riparian Woods where Ardatha and her Heralds were making their way on a quest Orrin never really understood.
What Orrin did understand was joining Ardatha meant Food, Shelter and protection. So, he convinced his brothers they should stay... even if it meant they had to put in work to serve their new leader as the pack moved on whatever grand quest Ardatha envisioned for them.
