After spending 3 hours going round in circles in my little, wooden adventurer, looking for other people, I've dragged my desperate self to ask for help.
In the travel section of Adventure, I only have a button to take me to my hearth fire. However, while fiddling with an alt (in no way sexually), I realised that there's a way to start around civilisation and, more importantly, get another option in that travel menu.
Ultimately, my question is this: Do you need to physically go to a charterstone to set it as the one you'll travel to, or is there some fancy alternative, for example via invitation?
PS If, in the very likely event that I'm buggered, I have another question: Is there any other way to find civilisation or is it a matter of plowing through the countryside?
