Deities walked the land, and not in the astral world… In the early Fourth Epoch, during the era of the Solomon Empire, there was no distinguishing between the worlds of myth and reality. Deities directly walked the land without the need for a descent?
This is somewhat similar to the Second Epoch as written in the City of Silver's books. The Giant King's Court and other locations are separated by a door in the real world. They just needed to pass through it and return the same way. Mortals and deities mixed together in the chaos and darkness… Also, the astral world really does correspond to deities… After hearing Viscount Mobet Zoroast's description, Klein instantly began connecting the dots.
He subconsciously swept a glance at Groselle, as this giant was very likely someone who had experienced the history of the Second Epoch!
Groselle picked up a cup larger than a wooden bucket and gulped down some melted snow as he laughed.
