Asgard is not really a three dimensional physical space, but in the Fireverse it has a geography suitable for the human to whom the story is told to understand. The World Tree can be reached from the top of a hill. It’s not growing out of the hill but is next to it and Odin is able to grasp one of the branches in order to hang from the tree. From that hill, one can look sheer down into forever. On one side of that hill there is a cliff with a stone seat carved into the hillside. There is a little foot path to the seat. This is Odin’s seat of seeing. From there, he can look into Jotunheim, or Midgard, or wherever. Just in front of this throne, the path broadens a bit and there is a short wall at the cliff edge, just right for Odin’s ravens to perch on.
On the other side of the hill stands Valhalla. It is just as described in lore, made out of spears and shields and having many doors and the Einherjar within, and a pig of unlimited bacon, and a goat whose milk is mead, and the triple throne where High, Just As High, and Third sit and rule. These are Odin, Honir, and Loki. Honir does not have a physical form unless he is manifesting between Odin and Loki. He sometimes manifests in the middle throne while Odin and Loki are both in their thrones. Odin sits in the sky throne, that is, the throne of air. Loki’s throne is fire and water. Honir’s throne is earth and ice. Just as it says in lore, the Einherjar go out and fight all day and then are resurrected and party all night in Valhalla. So, the Einherjar are not there during the day. In the Fireverse, Odin holds court in Valhalla in the day, with a lunch for any gods who want to drop in; when he’s not there all these processes continue to happen.
