Azathoth is an ancient entity that exists as a hive mind across seven separate dimensions which are linked to each other. These dimensions border a lower eight dimension known as the mortal plane. The seven revolve around the eight, the latter of which contains the known universe and all its inhabitants. The ultimate goal of Azathoth is to re-unite with its separate pieces in order to make itself whole. To accomplish this, each piece must individually descend to the lower plane, and wait for the other shards of itself to arrive. Once all seven pieces are within the same plane, they can fuse themselves together to create Azathoth's original form and complete the deity's goal. This would allow him to ascend back up to the astral realm as one being. However, as eldritch beings exist outside our realm of existence, they have no concept of the passage of time. As such, they are blind to the movement of our reality, unable to determine what period of history that they enter. Since eons can pass in the blink of an eye to them, it makes it very difficult for the deity to coordinate amongst its various shards, drawing out its goal across thousands of years.
All of this makes the deity's goals more convoluted, full of hiccups and adding to the amount of things that could go wrong. The complexity of all these steps drastically slows down its time frame, and makes its goal more expensive, requiring much more time and energy than should be necessary. It would be far simpler to build a doorway between the seven dimensions that it exists across, uniting each of its pieces quickly without fuss and drastically cutting down on time and possibilities of screwups. The plan it had adopted would be the equivalent of going from New York to New Jersey through Texas, despite the former two being right next to each other.
Why would descending to a lower plane of existence be essential to assemble itself?
