All of the party, including Elden, entered the Enclave and climbed to the top of the Tower of the Moon.
There, they all discussed in more details what was happening.
Elden told them that the elves had created a plan that needed the help of a priest of the church.
According to Elden, Terra has a sickness in her, and that was the very existence of the Darkness.
The elves were planning on traveling to the Darkness to destroy the sickness in her.
After some prodding, Elden confirmed that the Sleeper no longer has contact with Terra.
Apparently, for the last few hundred years, Terra had been growing more and more erratic in her dealings with the Sleeper.
The last few Sleepers were beginning to die, and the last proper Sleeper died after a few days.
So the elves decided to basically put the Sleeper in a dreamless sleep, so that they would be safe from Terra.
