Hey Fenris, I'm very happy to see you enjoyed the update!
The rankings depend on you good (or bad) you've been to Asterion. It's a little more clear now (I hope) with the line bar: as your affection increases you go from calf, to snake, to peacock. Within those you get bronze, silver, gold and platinum as you go up, with Great and Grand indicating if you're halfway between these.
If you've been a very uncaring master you go past below calf and start earning points in the opposite direction, that's when your ranking changes from Great/Grand to Fearsome/Ruthless. So, Fearsome Silver Snake is lower than Grand Gold Calf, which is lower than Great Silver Snake. It's a little confusing but it's a fun way for us to track how affectionate players are being to Asterion on averagem, as opposed to printing a number on screen and telling you to remember it and write it down on the survey.
