Beyond the Equestrian borders lies a frontier filled with magic and mystery, history and treasure, but also incredible danger. A young Pegasus named Dusty dreams of making his name and fortune by scouring these lost lands for ancient artifacts. But Ivory, his childhood friend and stalwart companion is always at his side—even if her magic isn't exactly what one would expect from a unicorn.

When their escapades run them afoul of the royal fleet, Princess Celestia sends one of her old guards with them for a mission that, unbeknownst to them, may change the world forever. Some remnants may be better left in the past, and others are timeless gifts, waiting to be rediscovered... but one thing is for certain: the friendships that these ponies make will last forever. If fortune is on their side, it will be enough to save them.
