Fex

"'You are traveling to Fex, which might be the richest new discovery for biotech in decades.' -Fayet Kellen"Fex was a planet once considered and rejected as a base for the Rebel Alliance. The red sun of it's solar system gave rise to an unusual purple landscape ranging from pale lavenders to deep violets. High silica and mineral content in the soils resulted in crystal structures. Many of the herbivorous creatures possesed crystalline spikes growing around their heads or on their backs. Some species could even withdraw their heads into a highly armoured body cavity. The spikes evolved to protect their wearers from brain sucking predators that lurked in the trees above.
