This bullshit space witch summoned me out of my universe and gave me the magic power of destroying anything I can fully conceptualize.

[Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is alchemy's first law of Equivalent Exchange. In those days, we really believed that to be the world's one and only truth...]

Un-fuckin'-fortunately, she was never that specific about what 'fully conceptualizing' means.
