Medieval history, the times where the clergy ruled the world, the kings were the judges of the people, those who disagree starts to rise up, came the people from other dimension, but also came the Paetra of inquisitors ready to meet and annihilate all who would place themselves on the way.

They call their world of Aerna, a naval post-revolution planet, this revolution was known as the Dark Ages, as each people had their culture, their leaders, their beliefs and the alien discovery only made it all collapsed, radical terrorize and it was pandemonium. Aerna's People are physically very similar to humans, but there is something magic conventional. They have strong links with magical beings of nature, with animals and with the physical elements. Some developed more skills to move objects with mind power, others could produce fire, make it rain, windy and various other things. You do not know when life started there, but obviously each had their theories. Some believed that there was a blast of energy that created Aerna, others Aerna always existed, others that the world was born from a giant egg, others had theories about gods and goddesses having fun with their divine bodies as they created the heavenly bodies and others believed Aerna that was the very goddess of life.

These conflicts had only end with the creation of Paetra, a mixed military institution, which had the objective of investigating all religious theories, maintain peace among peoples and was the primary authority over all kings. With the power to tie and mediator in all matters which concerned the management of people. All took place in society except the anamagos, those who passed the magic test, they should be cut off to prevent the weakening of races, also because his blood brought into the world only traitors and murderers and thus war and death. So the inquisitors were always prepared.
