This story is a sequel to Alone

Tempest decided to stay in Ponyville for a short period, helping with miscellaneous tasks. But in that time, she receives an invitation to a special night in Canterlot, where she meets an unexpected face that sparks memories of old.

This is a sequel to Alone but it isn't required to be read as this story can stand on its own. Though it may spoil some things in the previous story.
