In the Empire of Splendour, children are told from an early age not to turn their back on their reflection, nor to gaze too long into a mirror. These are not merely warnings against vanity. Mirror spirits are creatures from the Underwater Darkness World who inhabit the reflections of intelligent beings and are able to animate them, step forth from the mirror and wreak havoc in the mortal realm. They are only able to inhabit a reflection if it is 'left behind', hence the warning not to turn your back on a mirror. Imperial citizens often walk backwards from a reflective surface until they can no longer see their reflection. In Vaarta, mirrors are made with shutters so that the reflection can be safely sealed away. Mirror spirits can only inhabit a reflection if it is singular and complete. In Oksa, mirrors are always made from multiple panes. It is also a tradition to disrupt the surface of a body of water if you have cast a reflection there. Despite these precautions, and despite the fact that it is rare for a mirror spirit to inhabit a reflection, from time to time they still cross into the mortal realm.
Mirror spirits are hedonistic creatures. They live for an excess of sensation, be it gluttony, lust or more macabre tastes such as torture and murder. They appear as the person whose reflection they have stolen, except reversed. The personality, however, is the spirit's own. A person who has had their reflection stolen by a mirror spirit no longer casts a reflection, until the spirit is destroyed or sent back to the Netherworld.
'Mirror Spirit' is an acquired template that can be applied to any intelligent, corporeal creature (the reflections of incorporeal creatures are too faint for the spirit to inhabit). A mirror spirit uses all the base creature’s statistics and abilities except as noted here.
Size and Type: The creature's type changes to Outsider, with the Spirit and Netherworld subtypes. Do not recalculate the creature’s Hit Dice, base attack bonus, saves, or skill points.
Speed: As base creature. Mirror spirits formed from reflections in water have a Swim speed equal to the base creature's normal land speed.
Skills: A mirror spirit has a +4 racial bonus to Disguise checks to appear as the base creature.
Challenge Rating: Same as base creature.
