"Signal to the Winter not to take any hostile actions," Byron immediately reacted, quickly speaking to the communication officer beside him while turning to look at Viola, who was gazing out at sea. "Why are your kin appearing here? Aren't the sea demons said to rarely stray far from Antawen?"
"I don't know either…" Viola looked even more bewildered than Byron. "I've lost contact with Antawen for several days. Could it be that something has happened over there…"
