As much as Prince Thomas had advised patience, things moved quickly once the idea was in motion.
Getting the various authorizations was ridiculously easy. General Seycomb couldn't refuse the nobles' pressure, and the same went for Headmistress Holwen. Khan didn't even need to talk to them to obtain their official approval and support.
Other aspects of the idea were also easy to plan. The Nognes families had armies of architects, technicians, and more, so a blueprint of the arena quickly took form. Everyone involved with the construction also forwarded various requests for materials, which Khan's faction was happy to provide and purchase.
