Many philosophers compare our life to a game: some players rely on luck, some on deceit and bluff, others go all-out to understand the inner rules, logic and mechanics and use them for their benefit. A Fiendmasters walk on uneven ground. The demons they control may try to switch places with their captors, and when a young fiendmaster Valianir Zimmer gets plunged into a wirlwind of events and emotions he has no influence on , one will have to wonder wether he is still a player, or if he had became a pawn in A Fiend's Game?

Rated Mature for: explicit sexual content and mildly foul language.

Trigger warning:
Humanoid-in-Equestria clopfiction. If that genre puts you off, I suggest closing the tab.
Contains a non-clop scene of rape.

Tag explanation:
Human: while protagonist is not strictly human, he belongs to a humanoid race.
Dark: killing demons, disturbing nightmares and some less-than-happy events. Also some nightmare fuel and emotional traumas.
Gore: There are demons out there, and protagonist is a demonslayer. Things are bound to get violent.

Note that if you are eager to get straight into action, you can skip both Intro and Tutorial (the chapters where there are no ponies) at the price of some understanding of what is going on.

Editors: AuthorGenesis did most of the work. Fistofbrick was a great help too.
The Eternal Black Flame helped at the beginning of the Intro, but dropped off later, so there is that.
