The druid shakes his head. "Cragmaw Castle actually. It used to be a castle, from the age of Phalorm. The goblins have taken it over... at least until it crumbles onto their heads. Look, the Emerald Enclave would love to have that nest wiped out, so if you want directions, I'll give you directions. At least you'll maybe thin them out a bit. Fools.
Now, Thundertree is infested with the dead from the eruption long ago, the twig blights you claim to already have fought, giant spiders, some strange humans walking about in black masks and worst of all, a very young dragon has made a lair in the tower. So I would appreciate not having to risk my life saving your foolish ones. Leave the way you came and be quiet about it.
If you need to rest, then get inside, shut the door and don't be a bother."
Is it a good idea to get to the castle at dusk? We would be travelling for the whole day, be tired and then try to infiltrate the castle? In reality that would be an awful plan. And camping near the castle would seem to be a bad idea, because there would be goblins everywhere.
I vote fast pace first day, then a slower pace second day (to get us at the castle near afternoon. We would still be sneaking up to it, and it would give us lots of time during the day to take out the castle.)
