–The Hobbit
Response: After you travel to Forest Gate the first player may draw 2 cards.
The path itself was narrow and wound in and out among the trunks. Soon the light in the gate was like a little bright hole far behind, and the quiet was so deep that their feet seemed to thump along while the trees leaned over them and listened.

You are traveling through Mirkwood forest, carrying an urgent message from King Thanduil to the Lady Galadriel of Lorien. As you move along the dark trail, the spiders gather around you...
The nastiest things they saw were the cobwebs; dark dense cobwebs, with threads extradionairly thick, often stretched from tree to tree, or tangled in the lower branches on either side of them. There were none stretched across the path, but whether because some magic kept it clear, or for what other reasons they could not guess. - The Hobbit
As you move through Mirkwood, hounded by spiders, the forest path forks before you...

If Stage 3B was Beorn's Path, add the Ungoliant's Swarm burden card to the Campaign Pool.
If Stage 3B was Don't Leave the Path, add the Lingering Venom burden card to the Campaign Pool.
“The forest is dangerous, but that was beyond what one might expect to find.” Mendor seems shaken. “I fear something is not right in the land. I shall continue to travel with you.”
