Ah that's right. Yes, it was a bit tricky for him: to fix the virtu Felix had the choice of:
a) using the existing anchor which would require necromancy (heresy)
b) removing the existing anchor which would require necromancy (heresy)

He couldn't fix the virtu without using heresy so he went for option b which would negate the original act of heresy rather than a which would support it.
