I was disappointed about the portraits thing. I guess they are remnents of the past left behind to educate and better the future of tomorrow. Also, I'm glad the hp fact one cleared it up for me on that part!
Know your Vegvisirs. I was drawing these, wondered why the different versions around the place. Nobody can figure out what Björks tattoo actually is, a Galdrabók one roughly done most likely vegvisir symbol
the valknut- vikings painted this on their shields to call the Valkyrie to take them to Valhalla if they were killed, Jake had this tattooed on his forearm in honor if his viking decent/roots. Along with some ancient runes.
