The seed is: nXLQRmRMZI
Starting location: -3608 -3215 (F5, "devcommands", "goto -3608 -3215")

This is how I'm going to play it:

- No map. It's not a huge island, so getting lost should not be a major issue.
- No portal, except placing a portal at spawn to activate boss powers, but the corresponding portal can only be built at boss alters. I brought in mats for the spawn portal so I wouldn't have to go back.
- The goal is just to master the island, whatever that means to you. For me that means I can go anywhere and build anywhere.

I, of course, know what bosses are there, which I would rather not know. I will say that there is no Eikthyr, and there is no Queen... Okay, the rest of the bosses are there, so it's shouldn't be too hard, but it's a start.
