Ermac had asked Falstaff to meet with him. In order to keep the conversation friendly, he arranged for the meeting to be at the Byzantine. The man's first impressions...could have been better.
However, it would not disqualify him from Eric's support. He would lend guidance and assistance to any who were in need. If Ermac could harness this man's talents, as he envisioned, great works could be accomplished. Everyone deserved a chance to prove themselves.
Awakened were never as they appeared to be. This Acanthus, could possibly, appear to be a fool by intention. Perhaps Falstaff was a Hidden Badass. Or as he suspected, a Lethal Joke.
Countless stories had Lethal Jokes. Everyone laughed at the clown...then they fell silent when the bodies hit the floor.
