Top cat: not sure what you mean by navigation. You can move either with your mouse or keys, but I think you mean where to go from my Relto (the little island that is your home when you first start). The hut holds a book to your neighborhood. That will get you to your "hood" and you will find instructions there to get to Gahreesen (a book in the nexus room) where you can get your Ki (and your own personal number and ability to talk more easily with other explorers).
Once you get that Ki you can click on the book on a nearby pedestal that gives you a Nexus book back home on your shelf.
When you have a Ki number, please post it here so that we can help you.
The pedestal outside the hut on your Relto will lead you to the desert and from there, clicking on the journey cloths, you will be able to get the first four ages.
Sounds like you have done the offline journey so you should have no trouble.
Hoping to meet you soon
Kate
