ASTA said I honesty haven't read any of the CSes for this RP. Though to be frank, I started messing around with electromagnetism after reading up on it. I draw power/ability concepts from real-world technologies and scientific mumbo-jumbo, or I recycle old material from past characters and fictional nations I've utilized in the various CRPS and NRPs I've been in.
Guess that explains how we came up with the same idea. I tend to do the same thing for non-fantasy characters.
