Hugin is the first raven wizards encounter in Grizzleheim. If you bring him the appropriate ingredients, he will brew you a potion of Fate-seeing.
Hugin has this to say about your wizard, “You have done mighty deeds indeed for a stranger. I will brew my potion now, but even without it, your Fate is clear. You will do great things and when you face the greatest of evils, you will emerge wreathed in victory. Go now, and face your destiny without fear…”
In Norse mythology, Huginn (Old Norse: “thought”) and Muninn (Old Norse “memory” or “mind”) are a pair of ravens that fly all over the world, Midgard, and bring information to the god Odin. Huginn and Muninn are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources: the Prose Edda and Heimskringla; in the Third Grammatical Treatise, compiled in the 13th century by Óláfr Þórðarson; and in the poetry of skalds. The names of the ravens are sometimes modernly anglicized as Hugin and Munin.

Although I am well versed in Pop Culture references, I do not claim to have caught them all. Let me know your favorites in the comments and if I’ve missed one you caught, let me know so I can add it to the list.
