Welcome!
1) A lot of skills are already implemented, several are not yet. Their influence in your abilities is complex.
2) There are no real classes. Character generation only sets start-up stats/skills, all races are still rather equal.
3) The start-up stats/skills depend on race, social and familiar background, childhood events ... get surprised.
4) Items may have quality and modifications. Your skill using them will be more important though.
5) You can create up to four chars per account, which you can not use at the same time.
6) So far there are: A town, a town quarter, a village, an outpost - and enough landscape to separate them.
7) It is not yet a final game. It is constantly developing. The goal is to play. As the development is planned in decades and centuries

- better plan your playing accordingly.
