Like many roleplaying sims in Second Life, Taure Ru has rules. The best way of avoiding rules for the casual visitor is of course to pay attention to the rules that inform you to pick up a visitor tag and wear it! However even then you should be mindful of your surroundings and try to dress in character at least.
Taure Ru is a mysterious kingdom, its origins are said to be dark, but no one seems to want to talk about them. However there is plenty of information around to give you an idea of the kind of roleplay that goes on in this mysterious land.
This is classic fantasy adventure territory with guilds, factions and characters who will be mages, warriors, assassins, musicians and dancers. The latter two are probably an example of where Second Life roleplay differs from more mainstream video game versions because dancers and musicians in Second Life are quite important when it comes to entertainment.
