Story: Heart of the Mountain

[Normal] This is one of two incredibly long stories that I'm splitting between two days.  The other will be up tomorrow probably in the afternoon some time.  The author for both is "The Descendant"

Description: Having returned to Canterlot for official purposes, Twilight and Spike grow increasingly ready to go back home to Ponyville. Yet, when Twilight recognizes signs of distress in the Sister Sovereigns, the princesses Celestia and Luna, her curiosity gets the better of her.

What she finds shows her more about her teacher than she could have dreamed...yet places her in tremendous danger...
