Fey
Some fey were strongly bound or associated with specific natural locations such as water bodies, landmarks, or other geographical features. These included dryads, nymphs, naiads, nereids, oreads, and fossergrim.
Another group that was easily identified were the hags.
One group of fey was confusingly called sprites, despite this being a specific name for one of its included members. All "sprites" were small, mostly humanoid fey, that typically displayed some insect-like attributes (such as wings).
Yet another diverse group of minuscule fey were the gremlins, who descended from goblins transformed by fomorian rituals. They included the fremlin, galltrit, jermlaine, snyad, and the plainsjan that inhabited the planet Anadia in Realmspace. Mites were also considered by some to be members of this group.
