(*) These are some famous breeds rarely if ever found in central Genertela but widely reputed or otherwise worthy of notes. Some very powerful characters might display their status by riding such expensive mounts. The prices are given for their region of origin, don’t hesitate to extract twice or thrice that amount from your players if they think their status can’t suffer an humbler mount
I also remember seeing somewhere a table to give horses personality (e.g. "chews fences" ), but I've no idea now where that was from.
