Despite the reactions of the Supremes being strange, Persia continued the explanation of the Foreign Armies that were planning to invade the Great Forest. Of course, the information spoken by Persia would have to get confirmed, and the Nations of the Great Forest would probably start their preparation. After the explanation of Persia, The Supremes told her to prepare her Army against the Endless Grassland. They shouldn't get underestimated as they are an entire Continental Region.
Naturally, Persia already had an idea in mind. She created plans for warfare before she even explored the Korr Region. After all, she recently attacked the Ork Subjugation Army during that time. Persia planned to create something similar to a Nation. Though, it might get complications as her plans stopped at the creation of the Inquisition.
