Construction beginning/end
The formation of the Empyrean Rose, and the Creation of the Ophanim and Dominion.
After the Empyrean Throne the Angels ask for a place of their own where they could rest. God agreed, if he had a place to rest, certainly, his angels would like one also, and so he created the Empyrean Rose. Every Angel in Heaven was given a home in the Rose and every Angel from then on would have one there as well. It was also during this time that he began creating and contemplating the creation to come more thoroughly. To help he created the Ophanim to manage the laws he made and the Dominions to help organize the rapidly growing number of Angels.
