Thats what happend::
Paeta barley escaped after she and her Phase Spiders ambushed the party. The heroes boldly started building a camp in the courtyard of the chelish fort without checking things oput first. So the Pahse Spiders decided to attack. After two PCs and 4 Phase Spiders died, Paeta went back to the Night Hag Haetanga and reported.
So how would the revenge of the two look? Assuming Paeta told Haetanga that the PCs were allied with Bikendi.
