Tail docking
My Lamb was naturally born with a short tail (I'm too used by now) but they were always interested in lambs' culture and traditions, since they were dying away. Tail docking was on of these traditions. It was a practice made in ancient times by Yngya to her followers so she would avoid her lambs getting injuired or dirty (like actual sheeps). That practice slowly became a tradition, seen almost as a "Rite of passage". This can be performed both by Yngya, a family member, or an expert. Once a lamb turns a certain age, usually 14 years old, they can choose to dock it or keep it, but it can be done at any age above if they change their mind. All it takes is knowing how it's done and a spell to make it painless. In Aza and Keru's case, they were not old enough, however, since Koka and Chazaq knew that they would not live enough to become 14, they decided to let them choose it prematurely and docked their tails before their deaths, and they agreed. I still wanted to experiment a bit what it would've been like for Lamb to have a naturally long one, but it wouldn't have been as nice.
