Since Thor was invited, the knock was unnecessary, and it didn’t matter either that the man just walked in. Loki just gestured at the large tank against a wall, with the loveseat (‘borrowed’ from elsewhere in the Inn) nearby, positioned for fish-watching. “Just there.”

It was a nice tank, for all it had started existence as several sheets of ice and some whittled ash sticks. Transmutation was useful magic, at times. There were plants and rocks, and in lieu of an actual filter, one or two of said rocks filled that purpose, sending bubbles up as part of oxygenating the tank. And of course, there were a large number of variously sized and colored goldfish swimming around.
