Book 3B of the EarthGate Saga

Lapis Opal Amethyst, youngest of the last three Trigems, takes part in the battles to regain Earth- and to regain her half-brother Topaz's mind.

Trixie Lulamoon adjusts to being in Ponyville- this time for much longer than her other visits.

Sapphiron Rubeus Emerald, the middle child of the last three Trigems, helps the rebels in Ponyville by obtaining materials for his Sacred Amulets.

Luna convinces the Protean Nations to fully support the rebels, forming a strong alliance with them.

CAUTION! The gore will be bit heavier than in the prequel. Also, if you're curious as to why it's marked "Romance" you'll see soon enough. Also, "Tragedy", because of obvious reasons.
