Erm... I phrased things in a manner that could be read in two ways a bit: Koraakan would be the one undoing the damage, not Rilon. The only things Rilon would be made do is first stop doing anything, and then leave the place. Thaler's request back then was actually quite elaborate, and "make it so that they will be unhurt" was a part of it, just as "keep them safe from Rilon and his schemes and minions" and a number of other permutations of "just please keep them SAFE from Rilon" were. 

(And no, Thaler did not really include herself ... the only protection she has derives indirectly from the fact that by hurting her he would be hurting the three, too. Basically, if the three left her behind and simply stopped caring about her - not that I could see it happening -, then according to the deal she made Rilon would be free to do whatever he wants with her...)
