Within the Grey Tower, and also beyond it.
The rainbow light cast from the crystal walls outside was neither strong nor dazzling.
It fell into the open doors of the Grey Tower, streaking in diagonally and covering the upper half of Tricino's face.
Looking up from Annan's position, one could just make out Tricino's smiling lips.
A silence persisted for a moment, then Professor Grey slightly lowered his head to look at Annan: "What's the matter, Your Sky Carriage Majesty?"
He revealed a gentle smile: "What are you hesitating about?"
"...No."
Annan first reflexively denied.
Then he stopped mid-sentence and squinted at Tricino: "Nothing.
"It's just... should I address you as Professor Grey, or as the Bone Healer?"
Upon hearing Annan's words.
Tricino looked at Annan with some surprise.
After a pause, he smiled.
Tricino praised: "A fine retort, Your Majesty.
"If possible, please do call me the Bone Healer."
