So, at this point, the main combat is finished. The bulk of the mercenaries are defeated, but the cleric is running away.
Mariana is unlikely to join the pursuit as she will attend to Odhran's body. Vinccenzo will keep an eye on Mani and on her. The other guards would only slow the PCs down in their pursuit of Solomon. (They will stay behind and manacles the prisoners.)
Plus, there is the other escaped mercenary to worry about. Tuck could try to get Mutt to track down that escaped merc, but I'm assuming the PCs will want to stick together and catch the evil cleric first.
