Runes

The runes come from various pre-Christian Germanic cultures. There isn't 100% concrete evidence that they were used for divination originally and how it was done, but they're used that way now!

I use the Northumbrian Futhorc, which is a set of 33 runes building off of the Anglo-Saxon Futhorc. The Anglo-Saxon Futhorc may have originated in Britain or Frisia. It's my understanding that the additional runes might be later additions by rune enthusiasts after the region converted to Christianity, but I find them useful anyway.
