Through the window in the compartment, a middle-aged man dressed in a complex magic-patterned robe can be seen standing quietly under the tree-shaped emblem representing the Barbarian Cave.
He is Horus.
Greya, being close to the carriage door, was the first to open the door and step out.
When Angel came out of the compartment, he vaguely heard Greya's low mutter: "As always, icy as the coldest polar night."
Angel was a bit dazed before realizing Greya was referring to Horus.
"Cold Winter Royalty" Horus—his title alone reveals that Horus specializes in ice magic as a wizard.
"With him in the room, probably wouldn't even need ice magic, could directly freeze Mermaid Clam slices and keep them fresh for twelve hours," Greya snidely whispered to the side, but didn't dare to say it directly; she was only muttering to Angel's ear now that Horus and Sanders were conversing.
