One world of Irish legend, shared with your friends

What players do
The images on this page show the art direction for the world. They are our visual target, not footage from the game.
Explore the Otherworld
Tír na nÓg is one continuous world, from misted marshes to ancient woodland. There is no set path through it. Players choose where to go and find out what is there.
Build a home
Players start with nothing. They gather what the land offers, make their own tools and raise a first shelter. Over time it grows into a settlement worth defending.
Survive together
Up to 16 friends share one world. Some build, some explore and some keep watch. It is enough people for a real community, and few enough that everyone matters.

The world behind the name
SIDHE is an Irish word. You say it "shee".
It comes from the old Irish name for the ancient mounds that dot the countryside, and for the people said to live beneath them. In legend, an older race once ruled Ireland. When newcomers arrived, they withdrew into the hills and into a world that lies alongside our own.
The best known name for that world is Tír na nÓg, the Land of the Young, where nobody ages and time does not run as it does here. It is beautiful and it is not safe, which is what a survival game needs.
