That's what happened.
After the incident involving the disguised members of the Dragon Worship Cult launching a surprise attack on the scholars attending the Solitary Mountain conference in the Fiery Flame Land wrapped up, only a few noticed that Ian and his companions had suddenly disappeared.
Aside from Tres, who was privy to this affair, those who knew chose to keep silent.
They were not necessarily the elites of their respective departments, but having gone undercover for so long, they had learned how to control their curiosity… and to maintain a proper silence.
So, after a period of time.
Late at night, a light rain.
Riding a deep blue scaled steed, alongside another carrying luggage with crimson scales, Ian moved briskly along the tracks heading north.
Two fae twirled and danced beside the horses and the young man, emitting joyful laughter.
