Once again, we see overconfidence play a huge role in this battle, and the old axiom, keep your friends close and your enemies closer, prove it's truth.
As noted, Keborgha was caught in a vice, a starving, fanatical army in front of him and allies who would like nothing better than to see him taken down several pegs...What happened was akin to rats leaving a sinking ship...
As to Ishan and his brothers, I personally would like to see the Sultan, in whatever form it will take, retire...and Rashid succumb to his eternal rest...
Looking forward to the next...and book 3 of The Watchers....
