Astral jellies are flying jellyfish native to the Astral Plane. They are noted for their strange relationship with time, which flows on the Astral Plane in their presence even though the Astral Plane is normally timeless. This property makes astral jellies particularly useful to populations dwelling on the Astral Plane. When unable to carve out hospices and nurseries on the Material Plane, natives of the Astral Plane rely upon the presence of astral jellies to benefit from natural healing, and to allow their offspring to mature, processes which can't normally occur on the Astral Plane.
A spellcaster can use the familiar class feature while on the Astral Plane to gain an astral jelly as a familiar. A spellcaster with an astral jelly as a familiar counts as if she were standing in that astral jelly's aura of normal time whenever she is within 1 mile of her familiar. This makes astral jellies a popular choice for spellcasters wishing to bear children while residing on Astral Plane. Accordingly, the males of many cultures native to the Astral Plane view spellcasting females as particularly desirable mates, and see astral jelly famaliars as a symbol of fecundity.
