Carapace

Carapace is the hard, interlocking, protective exoskeleton with which chasmfiends are covered.
When killed, chasmfiends attract an unknown type of spren, which appears to be silver in color and is similar to a wisp of smoke. They float out of a freshly killed chasmfiend's body. In a symbiotic relationship with the chasmfiend, they are part of what allow the creatures to grow to the size they do with such a carapace exoskeleton. (Along with a high-oxygen, lower-gravity world.)"Smokespren"
The Parshendi have orange-colored carapace, like armor which appears to grow organically on their bodies.
