Fia

The Fia are creatures of whimsy and chaos. They live in hidden places, in spaces between spaces, in dreams and nightmares. They do not appear to actively seek to create or expand chaos -- they are content to dwell in whatever places logic and order can not reach.
It is unclear whether the Fia are creations of the Precursors or the Sien Beasts, and what their purpose was. Neither group seems to have paid them much attention, so they are unlikely a direct participant in the overthrow of the Limax, thought stories seem to indicate they originated in this period. Some speculate that they may be the initial, unworthy experiments of the Limax in creating new Sien Beasts.
Most Fia are small -- less than two feet tall. Their size and shape vary as much as the Sein Beasts -- perhaps moreso as Fia can mate with others of their kind, producing twisted, horrible offspring. Due to this curse, they tend to stick with others that are as similar as possible with themselves, resulting in many recognizable subspecies among the hordes of singular designs.
These beings do their best to avoid mortals. Their curiosity, however, can get the best of them, and often results in altercations. Fia are not overtly destructive -- they will use their abilities to escape capture, and prefer to inflict temporary or embarrassing situations to distract their captors.
== Fia-kin ==
Some Fia held very human-like appearances, and insatiable curiosity. These set out to explore the mortal realm. Some managed to enchant and mate with humans. The resulting offspring are known as Fia-kin -- mortal beings who retain some abilities of their mystical heritage. While they tend to be rare world-wide, in villages near the homes of these curious Fia such beings may group together and set out to form their own communities where they can explore both sides of their natures.
