We're Class

These are the only four centaurs living in Winter Hill, and they're all great friends with each other. There are taverns that have to overcharge them in case they drink all the ale in the barrels. There are others that sometimes let them drink for free because they come so often.
From left to right:
Morwyn Rowland: A martial artist, who has travelled to the Tsunami Islands many times and is sometimes called Morwyn-san.
Elverum d'Artagnan: A fencer, who was born in the north of Ysgaron but lived in Winter Hill for most of her life, and also crewed on the Gods' Hammer.
Bron Bowman: An archer, whose family have been archers for so long they don't even know where the name comes from. The rest of his family live in Tantalon.
Inrain von Sturmberg: A jouster, who is of noble blood but ran away. His family are the lords of an area in the north of the Antaco Range.
Inrain and Elverum are both named after towns. Elverum is in Norway and Inrain is in Austria.

Centaurs are natural athletes and have fantastic stamina. This is because they have, among other biological quirks, two hearts.

Look at the colours of the horse parts. That's symbolic, that is.
