There would be many obstacles in his path to increase the Astral Artisans' reputation amongst several races.
It was an ambitious plan and Shane was fully aware of the difficulties. However, even if it wouldn't work out, he was sure that the ballistae Dyr and Han could produce would always stay in demand.
Had it not been the case, they wouldn't have been purchased for 4,000 gold coins within 5 minutes after he had exhibited them in his store!
Furthermore, Shane had yet to increase the number of races that were able to access his shop, because currently there were only four races that could purchase something within his shop!
Once Dyr and Han would be proficient enough to create an aesthetic-looking ballista as opposed to their first try that looked crude and hideous, Shane would enlarge his shop!
It was unknown if Dyr could share this blueprint with others because it was bound to him and Shane wanted to test if duplicating the blueprint was possible!
