(Of course someone has done a Steampunk Princess Leia fanart. From http://blendover.tumblr.com/post/235179932/steampunk-princess-leia)
Name: Princess Leia Organa of the United Kingdom
Age: 26
Birthplace: Officially, on the ironclad HMS Eris en route to London from Hong Kong, adopted by the Queen and brought up as a Royal Princess amid much speculation about her true parentage and birthright. 
Based on: https://en.wikipedia.org/wiki/Princess_Leia 
Powers: Initially does not believe herself to have powers but will later discover "The Forge". Powers similar to Star Wars canon Force powers, so levitating objects, influencing people etc. 
Equipment: Nothing special initially other than intelligence and royalty. Some kind of lightsaber in future. 
Bio: A businesslike woman who works as a diplomat for the Crown, but who has a sometimes stubborn streak; is philanthropic and also hides a softer side and a fondness for charming rogues; people that do the wrong things for the right reasons. Fiercely honourable and patriotic, she works for MI6 in secret. 
Extra: Edited a little; I'd originally put her surname down as Windsor but it's a little early for that so I removed it. Five feet tall. 
Skills: Brought up in the nobility but a tomboy so preferred riding and shooting to dancing; a good shot with handguns. Some knowledge of languages through her background in politics and diplomacy.
