Forsythia

Pyroclastic Geode Subspecies

Some dragons hear the call of their ancestors more strongly than others, and they leave their earthly bodies behind during their first adult molting. Usually, these abandoned vessels are taken back into the environment from which they were birthed, through immolation, decomposition, petrification, or other means.

Occasionally, these dragons are recalled to their bodies to serve out a higher purpose. When the Earthshaker calls back one of his Snapper children in this way, a Geode Dragon is born.
However, even more uncommonly, a dragon of mixed lineage may hear the call of multiple ancestors. When Snappers, Coatls, and Obelisks are strongly spiritually connected to both the Earthshaker and the Flamecaller, they seek out an active volcano and bury themselves in the ash, cooling lava, and pyroclastic flow to ascend to their exalted calling. As their bodies sleep, the heat and pressure of the volcanic atmosphere changes them, creating a metamorphic wonder. A reawakening of these special dragons from their slumber results in the birth of a beautiful Pyroclastic Geode Dragon!
