It was not uncommon for ships to come across pirates during their voyages. Hence, they must be equipped with cannons or even needed assistance from fast boats to help them in moving forward.
If there were valuable goods on the ships, the crews would invite Space Mages and Wind Mages to escort their voyage. There's no smoke without fire. Wind Mages could control the direction of the wind and allow the ships to move forward quickly. And having Space Mages as their guards, they could transfer the goods to a secret place in emergency situations.
In the epic, there were also Advanced Space Mages who specialized in providing security to the goods. If the ships encountered natural disasters or pirates, Space Mages would use magic to teleport the whole ship by changing its world coordinates, allowing it to escape from the danger.
