He ducked under the door out of habit; Midgard was built for smaller men than Thor, and this place seemed very similar to Midgard in build. "I think it has simply been... placed differently."
Once they were outside, Thor stretched his arms a bit. "No," he said. "I feel as though calling it may not be the best of ideas.

Not that this didn't happen fairly regularly in other realms, but they tended to be at war. And he had no reason yet to be at war with this place.
"Perhaps not yet; perhaps she was awaiting my capture and will reveal herself soon." He glowered down at Loki. "Do you not remember how she tried to replace me at my death with the troll Ulik? Pah."
