Lyle gathers a list of people who are unaccounted for, updating it as he gathers new information. While most of the village's population made it into the keep, a significant percentage (something in the high single digits, let's say) are possibly stuck outside. They might well gather in the town's second-safest location, the temple of Chauntea, but a house of worship dedicated to the Farmers' Goddess is hardly a fortification; they'll be in trouble if the raiders aren't just following the path of least resistance, although it's a good bet that the kobolds at least will do just that.
Mornok locates a distincly nervous-looking guardswoman who directs him to check in with the town's Sherrif, one Tarbeck Reyne, who is conferring with Red Ascot, his castellan, on the second floor of the keep's main tower. (The town does have a Mayor by the name of Hillister MeKnight, who presides over trade agreements and acts as a justice of the peace, but in a crisis situation like this, the Sherrif's usually-ceremonial authority puts him in charge of the emergency response. In a larger town, an arrangement like that would be likely to result in the Sherrif being corrupt and possibly arranging just the emergency which justifies him seizing power, but talking to the folk of Greenest for five minutes will confirm that Lord Reyne is a lifetime resident, well-known to those in the know, and almost universally trusted.)
