The English names for the days of the week come from the Vikings. They named each one after their gods, and it goes as follows:
Sunday, the goddess Sol, who was the personified Sun.Monday, after Mani, the god of the Moon.Tuesday for Tyr, the one-armed god of war. His hand was lost by allowing Fenrir, a monstrous wolf (and Loki’s son), to bite it off, because only then could the beast be imprisoned.Wednesday for Woden, better known as Odin, ruler of Asgard.Thursday for Thor, god of lightning.Friday after Freyja, goddess of love, sex, and violent death.
#9 Odins ravens were named Hugin and Munin.
Runes were not magical, they were letters just like the abc we use today.
#11 The wolf that tok Tyrs arm was named Fenris.
In fact, Vikings weren't more or less brutal than other warriors of eastern Europe. They were described as if only because writtend sources were written by clergy, which were targeted by first raids, when Vikings were payen. Because no christian would attack a church and Christian church wealthy it explain why first sources talks about Vikings as calamity and stop at the moment Vikings convert themselves to christianism.
