I am a 21st Century Boadicea/Boudicca....

[HoneyandRum]

I am a leader of armies, ruthlessly impaling my enemies, I am powerful, wise, cunning, tactical, physically strong and intimidating. I inspire loyalty.

What is my name?

Ottilie - 'prosperous in battle'.

Thank you Frumious. (With your magnificent, if bizarre name! )
