For the majority of her life, Elsa was a kindly, well-disposed old dear, living a sedate life as a matron in a small Swiss mental institute, and lovingly restoring her patients to sanity. An unfortunate mix-up in the drugs cabinet one day led to Elsa swallowing some experimental psychosis treatment drugs instead of aspirin, and the effect on her personality was quite...shocking. Elsa's preferred curative method ceased to be restorative walks in the garden and quiet reading, and instead became electro-shock treatment, administered for as long as was possible without blowing the fuses.
