Unlike with Lanie, Ves saw no need to witness the Inferno Spear Prince's attempt to recruit Taon.
Ves did not enjoy the company of the former Ylvainan anymore. Their last meeting had already been awkward, and he did not think he would gain anything useful from hearing from him again.
Though Ves honestly did not think that Venerable Taon deserved to become a protege of the legendary Destroyer of Worlds, it was not his business to interfere with their business.
Venerable Taon would be able to work for the Rubarthans regardless of what Ves thought once he officially severed his ties with the Larkinson Clan. His opinion towards the Larkinsons would only deteriorate further if he was met with obstruction.
As for the Destroyer of Worlds, Ves had no power to influence her decisions. She may owe a lot of gratitude towards him, but she was a lot older and wiser than him. If she thought that it was worthwhile to take Taon under her wing, then that was her prerogative.
