The Crusaders sometimes form conclusions and make decisions based on impulsivity and gut feelings rather than rational thought. So, when they meet Ponyville’s newest, specialty flower vendor—a young, quiet mare from Alemaneia named Schneeblume—Scootaloo immediately begins to suspect something… that behind her quiet exterior, that bright smile, and those kind eyes, she's hiding something sinister.

Well, technically, she is... but perhaps not in the manner they expected.

In the end, the three quickly-growing fillies may find that their cutie marks and their penchant for helping ponies may come in a different fashion than they're used to.

This story is a sequel to The Flower Mare: Seele

Schneeblume Herbstlicht—Ponyville's newer Flower Mare—was a withdrawn, grizzled earth pony veteran of the The Great War. It took the determination and attentiveness of the three Crusaders over several years to help Schnee slowly find peace in her tumultuous mind, and life. But it turns out, in a manner of speaking, there is one more battle that must be concluded.

And to lay to rest some more of her demons that have haunted her healing mind, Schnee realizes she must once-more return to where her journey through Tartarus began: back home.

Two-chapter, third and final installment of 'The Flower Mare' series.
Unlike my previous stories that had sequels, this is one that I highly recommend reading the previous two prequels for better world filling.

After Planet Aether has been brought to peace and stabilized, Samus Aran doesn't get much rest when she's sent to reconnoiter a nameless planet on the edge of Galactic Federation space. Ostensibly, she was supposed to determine the size of a Space Pirate operation that was mining Phazon on this planet... and mark the place for a quick strike by Federation forces if it came down to it.

But when things become much more complicated beyond what her mission brief had stated, she may find that her fate and those of some unlikely allies may be intertwined. The battle that rages on the ground in a fight for survival and duty may have Samus questioning herself when a new front in an undeclared, nameless war is opened... in her mind.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)
