we'd run around with packs of wolves through the forest and our roads we'd made. There would be pups born all over the place. Realized eventually that they grow up when you are not around. Went deep into the woods near a castle we built to farm some wood at night. Noticed that I had wolves defending me while I cut. Didn't take them there. pretty cool.

Edit : I made it a mission to tame a 2 star and replace our entire population.
