The Cosmosiren... the most powerful starship in the universe... Well... maybe a little less powerful than the TARDIS, but still more powerful than the average, and also more sexy !

This cutaway view of a Commeta Class Cosmosiren in action show the internal organisation of her body.

...But where do the cosmosirens come?
Basically, a cosmosiren is a genetically engenired and biomachanical chimera essentially based on the Elviana's Leviathan Siren species. Moreover, the very first cosmosiren "prototype" was born of a Leviathan Siren who worked for the Ttrucilian Cosmosiren project ^^

...Ok, but, how do they move?
Well, to displace their huge masses (even if the cosmosirens are not so dense : for exemple, the length of Igaria is equivalent to 15 times the Earth diameter, but she is "only" 20 times more massive!), cosmosirens use a spatio-temporal distortion generator that deforms the space (and so, modifies the gravity) in the front of the cosmosiren and restore it behind her.
At small speed, the cosmosirens "surf" on a gravity wave that pulls them forward, and at full speed, they move just like in Star Trek , by shortening the space between her and their destination and lengthening the one between her and their starting point. :-P

This is a pretty elaborate work I made some years ago, and that rediscovered lastly... I had just to add the text before to upload it !
I don't remember why I didn't post it before... I probably wanted to use it as a part of a larger project.
