Shadow Knight

A Shadow Knight fights dark forces with their own darkness. They complement their fighting skill with bits of dark magic they have through secret rituals that bind them to mysterious dark forces. Due to their dark nature, they are often viewed with suspicion and fear.  Most Shadow Knights belong to secret orders on the fringes of society, rarely mixing commoners.

Shadow Knights are often sought out by nobles for their personal guards or as elite soldiers for special missions. In return their Order may demand substantial financial compensation, or political favours. Many Orders have a reputation for discretion and non-partisanship in political rivalries within the nobility.
