Hidden Temple

First, a bit of revision to the flyby attack. Remembering that one of the PCs is wearing the Dragon Cult Necklace, the encounter could play out with a twist or two. We'll assume they haven't worked on unlocking any power that it has yet, so when they make their saving throw against the breath weapon of the dragon, use their result to reveal the ability it has of flight. If they succeed, they can suddenly soar out of the reach of the dragon, narrowly avoiding any damage. If they fail, have them mysteriously find themselves out of range taking partial damage.
One aspect of this change is that in the aftermath of the encounter, a new consideration of the necklace and its power would be kindled. This, coupled with the need for healing, prompts the townsfolk to suggest a journey to the Hidden Temple of Lathander. Located high in the mountains on the western shore, the temple faces east across the valley toward the rising sun. Given the remote area and imminent dangers from the wild villains, the temple is concealed for protection. The location is generally known, but no one seems to know exactly where the temple is. At least, no one openly admits it.
Upon returning to the inn to prepare for your journey into the hills looking for the temple, there is a tentative knock at the door. Turning, the party sees Eric, companion to the half-orc adventurer Laramie they met on their first trip through Faring Ford. He asks if you are planning to go out in search of the hidden temple. With any affirmation that you are, he will relay the message that his mentor sent him to you, and that he would like to speak with you before you leave. Laramie is preparing to leave town and waiting at or near the warehouse.
Laramie is a man of few words, who likes to keep to himself as much as possible. He is an adventurer, and has shied away from much contact with civilization. He feels misunderstood, and prefers to keep to himself. The consensus that all orcs are evil wears on his mind, and he has chosen a life in the path of Lathander as his calling. In truth, he is a paladin of Lathander, and part of the defenses they employ to keep their temple concealed. But, like a cloud before the sun, he understands the winds of change can clear the sky and let the sun shine through.
He offers to lead you to the temple. He tells you the priests are secretive and guard their secrets closely, but believes he can convince them to speak with you and together you can persuade them to take a more active role in the world around the valley.
