.While in Asgard, time does not flow the way it does in the mortal world of Midgard. You can spend as much time as you desire fighting, forging, and visiting locations in Asgard without worrying about time passing in the game as a whole. This makes Asgard the ideal place to grind for levels.
.When on Midgard, time does flow as we are used to. Visiting any location will take up time, bringing you closer to the eventual sealing of the portal to Nifelheim and the end of the game.
