The Laine people had little experience in sailing.
Their land being surrounded by enemies on all sides allowed only a tiny bit of their border to connect to the ocean.
As a result, the standard of Laine's seafaring was poor; at best, they could only manage some river transport ships within the country.
The massive ship they were on for this voyage had been hastily constructed with a lot of fantastical elements thrown in.
Just a few days out at sea, the Laine people on board found themselves severely seasick.
The shape of the ship's hull was problematic; it would rock for a long time with even minor waves. It seemed that they hadn't prepared enough ballast, causing the ship to sway violently.
However, the ship was crewed by elite warriors, so they weren't actually vomiting from seasickness, but after two or three days, everyone looked pale, and no one had rested well at night.
