History

Known as the elder of the remaining non demi god like elementals, Gaia got her nickname for her want for slaughter and destruction. Though noted to appear as if an elderly pakob who has lost her way, the true history of Gaia is said to be far darker. Having been created through conflict, the elemental would rise to protect the rivers and lands in response to the dragons taming the lands hundreds of years ago. During the time of settling, these creatures would burn and conquer anything and everything. The few creatures native to Crakec would be turned to slaves to serve the despotic creatures, and it is said through the blood of those in chains Gaia would be born. Though other sources say her origin was from the dark continent but yet with a similar tale of one tribe of monsters conquering another, to which those who had lost were left so ablaze with hatred that Gaia would be created from there deaths as each would soak the ground with there deaths. Whichever story you believe, the truth comes to it that Gaia was a creature born of hatred and pain, and she is now a being of power and vengeance. As her circle of druids live to feed and serve her, it is said that Gaia arrived in the rivers only a few years before Yacyroxr would settle, some believe this was the start of the dragonlords terrible luck. As she would settle, it is said that Gaia would immediately begin kidnapping children through her allure, mostly pakob at first but then kobolds and dragons as well. Each child seemingly gifted with divine powers and an understanding of plants. Through each new addition to her grove, she would plant a seed within them and force them to serve her in order to protect nature itself from the vile hands of mortal creatures. Those she found to resist or who would break free are said to have found there gifts for magic lost and there minds broken. 
Those few adventurers brave enough to attempt this vile creature should be prepared for her warm embrace. That motherly love can easily fool even the most charming adventurer. Do not fret, few adventurers are known to accidently run into her, only those with druids within there party should ever fear reatalliation from the creature. For she sees all others as non threatening should they respect the forest and its rules.
