House Heterodyne

The House of Heterodyne is one of the most revered and most feared of Europa's sparky lineages. Originally founded by mongol-like warriors, the Heterodynes established Mechanicsburg as their home and went on to terrorize the surrounding countryside for generations. The created the imposing Castle Heterodyne and the fierce Jaegermonsters.

Then the Heterodyne boys, Bill and Barry came along. Raised primarily by their kind and upright mother, they renounced the ways of their ancestors and took to doing Good. The managed to stop a lot of the fighting in Europa before they disappeared during the war with the Other.

With Bill and Barry gone, the House of Heterodyne was considered extinct. Unbeknownst to the world at large, however, was Agatha Clay, raised as a normal child but secretly the daughter of Bill and Lucrezia Mongfish and heir to the Heterodynes.

Agatha's existence isn't so secret anymore, and there's a lot of chaos that's followed in her wake.
