Abyss Knight[edit]

Submission to the Abyss[edit]

The abyss knight defining trait is his patron on the abyss. Each knight has bind himself to one of the most powerful entities on the cosmos, the demon lords. The relationship between the demon lord and his knight is usually that of a general and a soldier, but without the rigid structure, due to the chaotic nature of demons.

Usually the demon gave the power to the knight because, for some reason, that knight could further one of the demon's goal. So, some knight live their lives under a mission for their demon patrons. Sometimes, however, demons give power to an humanoid just to see him create chaos and destruction on his way, or even just to see the humanoid soul pathetically struggling to keep his humanity under the demonic influence.

Great Warriors[edit]

Abyss Knight are accepted by their master for many reasons, but there's a constant: all chosen to become knight were good fighters, possibly the greatest of them or the ones who have potential to achieve greatness, either because their are smart combatants, violent monsters or great leaders in battle.

Creating an Abyss Knight[edit]

As you create your Abyss Knight, think about why your patron have accepted you as a protegee in the first place, giving you your current powers. Why did you choose to serve a demon? Was an act of despair after suffering a crippling or deadly wound in battle? Have you been contacted by an emissary of your patron, impressed by your potential? Have you looked for him expecting a easier and faster way to achieve power? Or maybe you choose to damn your soul in exchange for power for a noble cause. Are you enjoying the new abilities you have access to, or you live afraid of day that your patron will demand a terrible deed from you.
