their are alot of norse gods and I have not addressed them all but I have addressed the ones I know. their are two different types of gods in norse mythology. the aesir who are from asgard, and the vanir who are from vanaheim.
in norse mythology theres this thing called the world tree it links each and all the nine realms(be aware I'm linking them in no specific order.) the first realm is midgard this would be the equivalent of our realm midgard is the human realm. then asgard this is the home to the aesir gods Odin, Thor, Heimdal, Tyr, nfleheim is the land of fog this place as you can tell is shrouded in fog all over. then theres muspelheim the realm of fire this realm is known for being a volcanic land. vanaheim home to the Vanir gods Njord, Freyr, Freya,. then there is jotunheim realm of the giants this is the ancestral home the giants. alfheim is the home of the elves. then thers helheim realm of the dead those who die of old or not in battle will come here. and finally svartalfheim/nidavller home of the dwarves. and those are the nine realms.
this is a list of my favorite norse gods number 3 is heimdal the watchmen god he is known for watching for the coming of ragnorak he is also known for protecting the bifrost. number 2 is loki the trickster god loki is known for a few things for one he figured out the only thing that can kill Baldur, Mistletoe and tryed to kill him with it. he also has 3 children jourmangander AKA the world serpent, hella his daughter(this is not her actually name but were gonna keep this appropriate). and finally and my number one favorite god Fenrir the wolf god in norse mythology he is known for swallowing Odin alive during ragnorak and getting killed by the god Vidar, he also was chained up in asgard until ragnorak he also took Tyr's hand, when his symbol was used in norse mythology it means both good and bad, bad cause ragnorak and good because the symbol respresents a life of struggle can have a light at the end. fun fact I think I might get a dog soon and I think I Might name it Fenrir.
