This is going to sound crazy, but...since you probably have an idea of what kind of stuff I was involved in, you'll probably be able to believe me.

One of the other Servants--and, I assume, their Master--was a serial killer. Gilles de Rais, I'm pretty sure. Whatever warped logic Caster was working on, the war itself didn't seem all that important to him. One night we were following this trail of residual magic along the river, and we...found his workshop.

[Waver shuddered, crossing his arms to try and hide that he'd done so.]

It...wasn't pleasant. So of course that'd be what I saw in that stupid Dark Field, right?
