Knowledge local untrained: 1D20+1+4 = [6]+1+4 = 11
So no more information than what you've already posted.
How far away are the half-elf druid Syndra and the possible strange sorcerer under the stump of a giant tree? Close enough to call on for aid on short notice?
Well, after Caerth rests, he'd only have four hours to find one or the other. He knows Syndra tends to camp out near the old ruins known as the Syhdyn. The locals tend to avoid it, as they believe it is haunted. It sits in a region of high hills and is roughly 16 miles northwest of Carnell. That is the most likely place to find her.
The attack on Carnell was likely visible from Syhdyn, so she might already be on her way. Syndra may not like civilization, but she's not heartless. At the very least, she'd want to check on the local farmers and ranchers to make sure they and their animals are not hurt.
I'd say Caerth could track her down in about half the distance to the ruins, so in 8 miles. That would be 2.6 hour to find her and then another 2.6 hours to get back. If he hustles, he could find her and get back in 2.6 hours. He'd take one point of nonlethal damage for the second hour.
Caerth has no idea where the sorcerer lives, if he/she even exists at all. Now, Othrer
might know where it is Caerth's old friend grew up to be a farmer not a warrior. His farm is roughly 3 miles outside of the village to the southwest along the trail that leads to Fort Symas.
DM's Note: BTW, following that trail, the fort is 72 miles away and sits on top of a low mountain range, which is surrounded by high hills and hilly scrub and grasslands. 24 miles to the north of Carnell, along the northern trail, is an old hilltop encampment that is used by travelers. There is almost always someone encamped there. Both Angus and Maur likely passed through the encampment before they arrived in Carnell. Another 24 miles northeast of that encampment is Hazepoint House. It is an old clan moot and is controlled by the soldiers of Belporte. Belporte itself, is roughly 44 miles west of the hilltop encampment.
Remember that Caerth, Phar, and Aureus arrived soon in Carnell than Angus, Maur, and Quinn. The six hours until the horde arrives is from the time that Angus rode into Carnell, not from the point that Caerth arrived in the village. So, Aureus and Caerth are likely already rested or partially rested by the time the other arrive, although they did spend some time helping to save villagers, but providing First Aid is only a standard action, so it wouldn't have been long.
