Spike reflects on his relationship with Twilight. Something particularly important is bothering him. Before him is the unknown, he is afraid of falling into the abyss.
After sensing his mother had become distant from him for some reason, Spike decides to travel to another world to find out answers and hopefully help his sister make amends with their mother.
The weak Princess sits on her throne. Guards—and a dragon—keep monsters behind the door. The Elements concentrate on a spell. Fewer guards return in each instance. And more of Spike is eaten by non-existence.
Decades change within a blink. The banishment of a sister, the loss of a student, has caused Princess Celestia to be distant when it comes to family. However, a baby dragon burns through her defence... but her past failures cause her to let go.
Spike, a dragon with a broken heart, leaves Ponyville to follow his dreams. And meeting somepony he wasn't familiar with was the start of a great friendship or even more.
Spike has survived the strain of daily life to find himself empty inside. Proven a worker, a friend, and a proper dragon—that search for 'something' never ends. Finally, on being led by a feeling, he winds up before Princess Celestia without reason.
Twilight is surprised, and a little concerned to receive an invitation to meet with Princess Luna at Canterlot Castle. Could she be wanting to settle a score over Nightmare Moon, or does she perhaps have another purpose in mind?
Both on the edge of adulthood, they found each other, but look out over a vast and terrifying time. Hand in hand, scales against feathers, they draw strength as they take the next step together. Spike and Gabby had much to look forward to.
