They call you Harbinger.

You are a Keeper, a sworn protector of the Realm, mutated by necromancy to keep the monsters that plague the land in check. But you are no ordinary Keeper. You are the most powerful Keeper of your generation. A genetic anomaly: the only living Keeper to survive the mutation with a positive blood type. You possess the physical might of a mutant and the forbidden spell-casting of a mage.

Now, a new terror has risen. An experiment to resurrect the extinct Elves has failed, unleashing a horde of "Abominations." They are twisted and infectious creatures that are overrunning the Middle Realm.

Keeper’s Vigil is a 193,000-word interactive dark fantasy novel by Lota Labs. It's entirely text-based, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination.

As the Abominations claw at the gates of the Inner Realm, you must uncover the conspiracy within your own Order. Traitors seek to bring back the ancient Elves to fight an even greater threat: the Anunnaki. But the price of resurrection may be the death of humanity.

Will you rely on your steel, your wits, or your forbidden magic? Every time you use your necromancy, your mutation advances. If you embrace your power too fully, you may lose your humanity forever and become the very monster from which you were sworn to protect the Realm.
