Lux didn't leave the Vahan Empire right away.
After leaving the capital city, he camped out on the meeting place that he had agreed upon with Cai and Keane, just in case they all got separated from each other.
Fortunately, he didn't have to wait for long because the two arrived at their meeting point an hour after the incident ended.
"Hahaha! You should have seen it, My Daddy!" Cai said with a smug expression on his face. "After you left, the Emperor arrived and punished the nobles who were responsible for rigging your Trial.
"Several other Rankers also arrived at the scene, and all their High-Clerics were busy re-attaching the limbs that were cut off from those bastards. Um, who is that silver-haired beauty that protected you earlier? She doesn't look familiar, but she feels familiar. I have a feeling that I've met her somewhere before, I just can't remember where."
