The spirits of the two legendary space ships, Finny and Rae! Finny being the scantily clad girl with fins on the right and Rae being the school girl with the horn on the right. Every ship needs an interface, and it just adds icing to the cake when it's a very healthy female humanoid. This is a very loose concept, so there are going to be very heavy changes in the future as to their design.

Respectively, Finny is hyper enthusiastic, and openly suicidal while Rae is reserved and calculated, portraying the natures of their respective ships quite accurately.
