The Chrysalis.

Proverb "Just when the caterpillar thought the world was coming to an end, she changed into a butterfly." A dangerous butterfly...
Ravaged by Rome, Morrigan turns her fear into revenge and now it is Rome who should fear her. Rome's taxcollecter Decianus Catus intrudes on Morrigan's father's funeral, flogs her mother Boudica, and then takes the Iceni people back to camp where the women are raped. He then sells them all as slaves to be taken back to Rome.. However, the Trinovante warriors save them all of this horrid fate. To survive, Morrigan turns her fear into fury.. Now Rome should fear her wrath.
