|Gamespyx has published an article about character classes in Horizons. Seems that every character there can be pretty unique:
"Your character can be further personalized by choosing to be male or female, fat, muscular, thin, young or old. At any moment you can choose to pursue wealth as a prospector or get paid for building communities where your friends create, buy and sell the thousands of items that are available in the world. You can learn powerful magic that can be used to fight, heal or grow. Or you can become adept at fighting or spend time chatting with your friends."
The game features literally millions of character customizations and features, an open-ended school-based skill system and advanced community tools, allowing complete management of player guilds, associations and towns.
