Sinvaders
They were different because each servers had a different story. Different events had taken place in a same timeline for each server, that's why you can't have a common backstory in Atys today.
Well, the “river of time ” event is supposed to have explained those differences; it allows some degrees of freedom to adjust at least the decor if not the story. I may add that there are at the moment more important different “details” such as the tryker governor ... :-P
Also I would see such an improvement as a mark of respect towards the artists who worked hard to make Ryzom good looking.
