? Planet Flerantorus, shards of humanity ?

No, well, she wouldn't have killed Clarissa's messenger or turned them into a slave, but she would have played some kind of prank. It's just in her chaotic nature

And how often did she play "some kind of prank" on Clarissa herself? Since her "chaotic nature" gives her no peace... Did "slaves" frequently burst into Clarissa's office (or whatever she has) screaming "I'm gonna fuck everyone here", huh? It's one of two things: either she "respects Clarissa" and doesn't touch her "couriers," or she "plays pranks" on everyone across the board. I don't see any other options...
