Groups of things - Mythology

In regards to the "Vanir Gods" section of this quiz, Frey and Freya should be acceptable for Freyr and Freyja respectively.

Kvasir is the only one that can be called Vanir here. Bragi was born of Odin and giantess Gunnlodd. Frigg is known as one of the original Aesir. Balder was born of Odin and Frigg, so he is also Aesir. Loki is a proper giant. We don't know much about Tyr's mom, but his two probable fathers are Odin or the giant Hymir. He doesn't feel very Vanir either. Meanwhile, Njord, Freya and Freyr's father was completely Vanir, was actually leader of the Vanir once. And he isn't included in the list. Please, make these corrections.
