The first thing Felix did after teleporting to Elder Kraken's mansion was place a handwritten lengthy letter for each of his companions on the living room table.
Then, he patted them with a soft smile and teleported to the council, not planning to stay behind and say his goodbyes face to face.
He was never great with goodbyes and the fact that he would most likely never return to the heavenly plane made it even harder for him to speak with Karra, Sekiro, and Miss Sanae.
Plus, he was banned by Lord Hades for exposing his leaving with his memories intact.
So, instead of lying to their faces, it was best to write down that he would be taking the reincarnation opportunity.
"I hope you live a prosperous life..." Felix uttered one last time and then he took off the moment he heard footsteps near the door.
After he reappeared, he noticed that Lord Hades was already seated on his throne all by himself.
"Are you ready?" He asked emotionlessly.
