[It occurs to her that the Emperor might want them to fail. She wouldn't be the first ruler to throw people at an enemy to soften them up. The "heroes" she's brought to Tu Vishan might be for that purpose, to fight whatever they're meant to fight, but not to succeed, just to weaken it enough for the Emperor to take it down.

She decides not to voice that thought]
