Ragnarok=the Traveler and Darkness

so on the video: traveler savior or necromancer i saw a post in one of the clips that mentioned ragnarok which is a norse myth that explains the eclipse. basically the myth is that a great darkness chases after the moon and eventually catches up and swallows it(the collapse). the traveler looks like a moon/ the moon (big, spherical, and white) and in the intro to the game it says an ancient evil chased the traveler or something like that. also usually in the myth the darkness is a certain animal, yep a WOLF! BAM!, ya i think it must mean something. tell me what you think also when i was by xur he said something like this "your traveller has a dark mirror" i don't know what thats supposed o mean but just post your theories and stuff down below.
