Non-grimdark Warhammer crossover! A bit 'Dark' due to violence, but otherwise not that bad.

Pinkamena Diane Pie, AKA Pinkie Pie, is a Mountain Earth Pony sworn to seek honour and death - one requiring the other - in battle as a Slayer. With her companion Rarity, a displaced former dressmaker and fugitive from the Canterlot Guard after an argument with an arrogant noble in charge of designing new uniforms, Pinkie seeks to brave the dangers of Equestria and regain her honour.

She....isn't doing a very good job.

Oh, she's got the laying destruction on evil and all that but the key part, the dying valiantly part, she doesn't quite seem to have grasped.

Watch as Pinkie takes the monsters head on with a giggle and a giant axe.

(On hiatus until I finish Justice Itself.)
