As the Summer Sun Celebration approaches, Twilight Sparkle and the rest of her friends have plenty of their own problems to deal with. Ponyville is packed with tourists, and they've got to work themselves to the bone to make sure things go off without a hitch, and Twilight may just have the most important job of all.

But fate is about to take a turn for the strange, and soon those problems are going to be the furthest things from their minds. A magical ritual has begun in the land of Equestria, and it's not in any of Twilight's books. It's dangerous. It's destructive. And there's no getting out of it. It's called the Holy Grail War, and it's about to engulf the entire town of Ponyville.

Seven ponies have been chosen to be Masters, and Twilight is one of them. The other six could be anyone, which means Twilight doesn't know who she can trust. Their weapons in this war are called Servants, heroes from the myths and legends of a far-off world, and they're like nothing Equestria has ever seen. And this war has a prize: the granting of any wish the victor could possibly desire.

But there are a lot of unanswered questions. Where did this Grail come from? What secrets is it hiding? Who is the mysterious Servant who calls herself Ruler and does she have the answers? Twilight is going to have to figure things out, and quickly. Because this game was originally intended to be deadly for everyone who wasn't the winner, and if she makes even the smallest mistake, Twilight Sparkle might end up being a casualty... or even causing one.

She couldn't have made it herself. A solitary bookkeeper, long disillusioned with the "dream job" of maintaining the Canterlot archive, becomes the unwitting guide to a panicked Princess of the Night in the deepest recesses of their voluminous libraries.

Deep underneath the shelves and scroll racks, through the perilous and twisting caverns and gnarled trap-laden corridors, he realizes she isn't just seeking a getaway from the pedantic Canterlot politics. She's seeking to destroy an evil as old as the night sky itself. An evil that...well, she couldn't have made it herself...

Diablo Crossover.

The Archangel of Justice destroyed the Worldstone to spare Humanity the corruption Baal infected it with. The force of its death knell shatters Mount Arreat and sends Tyrael hurtling across the endless planes of reality. He falls upon a world untouched by Angel or Demon, far from the sight of the High Heavens. So far, in fact, that he fears he will not be reborn from the Crystal Arch.

Wounded and near death, hope appears in the form of two strange creatures bearing the power of night and day.

Tyrael now faces a time of recovery as his power slowly heals within a body fashioned for him by his saviours. Justice Incarnate tastes for the first time the life of a mortal, and it is a strange, confusing experience .He has been left in the care of one Twilight Sparkle to learn of this world.

After all, where better to find peace and harmony than Ponyville?

As she struggles within deepening conflict, she must push on and fight for what she believes in.
