Opposite a proud Canterlot cemetery amphitheater, stands an 8 foot tall obelisk. That obelisk is Equestria's Tomb of the Unknown, a monument to all those noble equines who gave their lives in defense of Princesses and Country, and whose names are lost to history and fate. Beneath the sarcophagus lies the body of an unknown pony from the Tirek wars. Inscribed on the tomb are the words,

HERE RESTS IN HONORED GLORY
AN EQUESTRIAN SOLDIER
KNOWN BUT TO FATE.

Several smaller crypts lied in front, honoring an unknown from other wars as well. A lone sentry from the finest of Canterlot's royal guard, having been trained and dedicated to perfection, has guarded the tombs every minute of every day and night, since the first unknown was laid to rest. NOTHING will deter him/her from their task of ensuring the unknowns rest in reverence.

On a solemn day of remembrance, the four princesses of Equestria pay homage to these honored dead.

Based on the famous Tomb of the Unknown at Arlington National Cemetery.
