Crestfall Summit

Crestfall Summit is the largest mountain in the The Silver Mountains. It is home to the largest population of Silverwings in the mountain chain. They live in the many caves that are on the sides of the mountain. Many of which are now stables for the Larrentell to use.
The top of Crestfall Summit is only slightly slanted, and as such made for a good spot for the Larrentell family to build their castle, Highpoint. It fills most of the top of Crestfall Summit, going all the way to the mountians edges.
Crestfall Summit is also home to the Blackiron family. They settled in a vast cave network within the mountain, and over time expanded it. Now big halls strecth throughout the mountain becoming mines the further down you go.
At the foot of the mountain lays Silverview, a small town that regulates access up Crestfall Summit via the only ground route. It was build long before Crestfall Summit had been explored, and used as a staging ground for all expedtions up the mountain. It was also the builders of Silverview that brought materials up the mountain and built Highpoint. After that the town started growing smaller, and now it's partly abandoned, mostly occupied by soldiers.
