Redwood was a neglected pup originally from another pack. He was bred alongside his five siblings to be taken advantage of and then sold when he was no longer useful. Redwood attempted to run away, and was put up for sale early because of that. Reed was in the market looking to buy herbs when he came across Redwood being sold, and ended up buying the pup.
Redwood's five siblings weren't as daring or as rash as him; they stayed put and obeyed the adults in the pack. But when Redwood suggested running away, his siblings agreed anyway. They were killed by a group of terrifyingly strong bulls, distracting them so Redwood could run away and be put up for sale by his leader.
