Vegvisir

Speaking to my Icelandic room mate Sol, she mentioned to me about Vegvisir, which is a Viking Compass with runes around that where meant to protect them at sea. I feel like this would be a great addition to the board game, as it could be laid over the map in the middle, very opaque but hinting at what it is. 

This could lead the children to research further into the topic by not knowing what it is and being curious enough to look it up for themselves. I am also thinking about having the runes on the outside border.

The teacher could also teach the children all about this before being played. I think it adds a lot of context to the game with the theme of the subject.
