[OS] Les trois hérissons avaient rendez-vous ce soir-là avec un contact dans un des bars miteux de la capitale. Comme à leur habitude, ils étaient arrivés séparément et s'étaient installé chacun à une place stratégique de la pièce. Sonia venait à peine de s'asseoir devant sa consommation lorsque l'odeur âcre d'une haleine chargée d'alcool souffla dans son cou. [M : vulgarité]

This is a Trevor mouse X Cyrus lion story.

A prince forced to leave a life he thought he would get, a life with a mother he barely knew, and siblings he had spent a year with in search of said mother. Victory was theirs, but at a price.

Living in an apocalyptic wasteland is not an easy feat, but Sonic, Sonia, and Manic all think they can handle it. That is until an oracle comes and tells them that they are not only siblings, but royalty, and that they have to travel the land and find their mother to bring peace back the peace. Its a big responsibility for these teens, but together they can get through it together.
