It's a mercenary realm that acknowledges the realities of politics. If Darka took every contract that was offered to betray their current ally, whoever that may be, they would quickly end up ostracised and ganged up on, and for good reason. KK is smart enough to know that. And so are you. So you don't want a greedier Darkan king, you want a dumber one. But for the record, no one in the king's council was willing to consider your offer. Darka just isn't a realm willing to sell its friends short.
