Huh, yeah that's bad. Catch and interrogate for more names and the new plans to screw us over? At our new wealth level I'd be fine with bookifying her too. Make a family set!No, the sister to one we bookified.
She hates us guts now, and she's a free crafter in Hell, having made several bullshit (like, seriously bullshit) items for Mammon's agents to spite us.
We have her True Name though, so no reason to be reactive instead of being proactive.
Given how this sister caseter combo goes they might have specialized in different stuff too. So could be worth it.
