Description:
Cover art for a short fanfic in which the four princesses end up fusing into one totally new being through a magical mishap.
“With an age-old monster set to return and intent on spreading destruction, the Princesses gather to use a spell left behind by the great Star Swirl the Bearded in order to ensure their victory – but they do not fully grasp the effects of the spell until it is too late.
Now all four have become an entirely new being, with her own thoughts and feelings, and she must face the reality of her situation: in order for the Princesses to return, she will have to die.”
