Assassin's Creed Valhalla: Dawn of Ragnarök

The last concept I’ll be posting from our game. 
This time for one of the more complex and demanding VFX, taking place over the main tower in Eitri. 
Although Dawn of Ragnarök unfolds in the mythological world of Svartalfheim, we always aim to have our work and visuals based on grounded natural/physical rules and too look believable. 
In this case the main inspiration comes from solar flare, cosmic magnetism and various effects triggered by light particles penetrating the atmosphere.
