"Indeed Master Zook," Goven answers. "Though they may not live." He studies the birds thoughtfully as they circle above the forest.
OOC-Can Goven tell from here if they are carrion birds or regular forest birds that have been disturbed by something?
To the others: "We should decide our course before we enter the forest, based on what we have observed from here. Where would be a likely place to find this castle? I am no great strategist, but a few thoughts come to mind.
"I wouldn't expect to find a fortress of any size in or near a swamp, but building near to a river would have some advantages, however, and it may be wise to follow it into the forest. They may also have built among the hills for defensive reasons. And there would have been roads leading to it by necessity, of which there may still be traces.
"These are my observations, but some of you probably know more of these things than I," Goven finishes and looks to the others for suggestions.
