The Alliance Council mentioned it as an interview to look for more evidence and testimonies if the Virandal Empire really broke the Alliance Rules. However, the alliance had an absurd requirement for the witness to share their window status. The reason was that they wanted to ensure the witness' identity.
"Can you calm down, and let's talk this out. Escape from the city does not resolve the problem, Ying." Old Man Gortham expected Ying would refuse to attend the witness testimony with those requirements. However, he did not expect that Ying would rather become the alliance's enemy instead of listening to the request.
