This was the last primordial that I was working on before my gamer ADD put me on a different project. It is presented here in case anyone can use it.
For what it's worth, here is an slightly related link to the Manus and the Pria. This appears to have been the most popular primordial detailed.
Notes:
does lots of damage to fungi, mold and spores. Let's include puddings and the gelatinous cube as well.
dimagnetic properties - levitates with magnets. Cannot hold them, but manipulates them with a latent psionic power.
Iridescent in appearance.
Immune to electrical damage
Very susceptible to fire damage.
