Creating this character was actually harder than I thought. For now I used the Arcane Background (Weird Science) edge for the Spark abilities, although this edge is probably not powerful enough. I also had some trouble coming up with the right powers for her. If any of my readers has some ideas how to improve the character built, I would be very interested to read what he or she came up with.
Agatha Clay (aka Agatha Heterodyne) (as at the beginning of Book 4)
Heterodyne Heir, Novice Spark
Pace: 6, Parry: 5, Toughn.: 4, Charisma: 0
Knowledge (Science) d8
Weird Science d10
Arcane Background (Weird Science)
Mr. Fix It
Wanted (By Baron Wulfenbach)
Agatha has built several clanks (including small, self-replicating ones) and worked on a couple of Gilgamesh Wulfenbach’s inventions while she was on the “Castle Wulfenbach” airship, but there were no fitting powers. When running a campaign inspired or based on Girl Genius, the GM definitely needs to add some more powers to emulate especially clanks and some other devices commonly created by Sparks.
