An unarmed auxiliary ship based off of the Royal Love-class cruiser hull. This was intentional, for it was desired that this ship be able to keep up with the Pilotmario Navy battle fleet. The class is designed to serve in various capacities such as hospital ship, fleet replenisher, and command center. As she is based on the Royal Love-class cruiser, she retains some of the protective elements of the warship.

Mercine is one of the two deities in Paternian lore, and represents all that is good. The other, Charas, represents all that is bad. Both have large pantheons of godlike beings known as Saints. When they were created, Mercine tried to do nothing but good, and Charas tried to do nothing but evil. However, in the process, they continuously destroyed themselves in the process as they were unsatisfied for there was some evil in what Mercine made and some good in what Charas made. They learned that in good things, there are some bad things, and that in bad things, there are some good things.
