Shattered Kingdoms

Daerk utterly forgot to make her give *any* vows or oaths when she joined up with the Talons, a fatal mistake, as it gives any Hellion worth the name the freedom to plot and plan to take over.
And dying lots to the Hammer was simply distraction, you'd have got suspicious if she avoided getting into fights with them much more than she did. Add in the fact she was usually pretty careful about who she talked to about her plans...

It did get back to Daerk after Shaco uncovered the plot and was threatened by Katsuko.

Yeah, I believe shaco did mention something about it to Daerk once but he didn't really believe it or think much on it and said he wasn't worried about it because she'd never get leadership over him until he was dead forever or gone.
