The Rose of Eternity is legend. In ancient times, it was said to be the source of all medicine, and ponies from miles around would come to it ailing and leave cured. Over the ages, however, its location had been lost to the sands of time.

After an expedition in the Tebitean mountains, the forces of Ahuizotl have rediscovered a lost artifact (through nothing but sheer luck). Now, Dr. Caballeron is researching the Rose…and learning it can do even more than simply heal ponies. It can…change them.

Their first successful experiment?

A black stallion by the codename "Double Helix."

His job?

Get the one thing that could stop Ahuizotl out of the way…fight Daring Do to the death.
