I've been playing Princes of the Apocalypse lately, and... (spoiler about the adventure)
On p. 41 of the adventure, in the Sighing Valley, the players encounter a griffon roost with mating griffons that have a nest with two eggs, which are described as worth up to 2,000 gp each. Since the book provides the gold value, I assume the egg is supposed to be sold (with some spoiling probability).
Where can the players sell it? It doesn't seem like Red Larch has anywhere with the infrastructure to incubate it, or any other close city.
On the other hand, travelling back to Waterdeep or Neverwinter takes more than a week, increasing considerably the probability of spoiling the egg (about 52% for a week travel).
So, can the players sell it in any closer town? Should they go back to a big city? Or aren't the eggs even supposed to be sold?
I'm asking this as a player for this adventure, but I'm also interested in the answer as a DM, since I might run the adventure in the future.
