While the Human races built their sand castles Ranagol came and made a pact with the Aquirs of Krán. They took his faith and he gave them his thirteen demi-god children (the oldest and most powerful is called Shackallor) to be guidance for them, who are actually barely (if any) more powerful than the noble Aquirs themselves. From this date the "Empire" of Krán started to grow slowly throughout the Eras as some of the Elves, Humans and Orcs moved among it's mountains and become the follower of Ranagol. Now Krán is the oldest existing country on Ynev. They fought many wars with the Demonic Old-Empire, the first Human inhabitants of Krán was originated from there as POWs.
Ranagol's religion is simple: change is constant, struggle is constant, and basically the two are sames, the individual always has to be ready to fight, to defend himself and what's his and to take what's others' so he can raise himself above others and ensure his survival. The Aquirs were doing this since forever anyway so they made a bargain. With the Demi-god Bastards they gained a cohesive force. Despite this the infighting is constant, which they find necessary anyway to weed out the weak.
The demi-god bastards traveled all over Ynev in the next few thousand years and searched for potential recruits. One of them found a group of elves who still harbor hatred against the Aquirs and try to hunt them down. Another found some entity with great power beneath the ocean then they fought and that monster-demon was so fierce Ranagol made it his first Chaos-Angel (there are many now, they are considered as aspects of Ranagol and the people of Krán worship Ranagol through them).
The Thirteen built a tower in the middle of Krán, which give them mostly safe haven. The structure of Krán looks like this: the closer you live to the Tower the more powerful you are on your own right, there's a movement from the periphery toward the center as everyone tries to climb higher over others, but the closer they get the more tougher competitors they have to defeat and take their place (and then defend that place from those who live outside of it). Even the Bastards aren't really safe, three of them were challenged and defeated. Their place were took over and three other being risen to demi-godhood and become the Child of Ranagol. I think that's enough about the Dark Empire.
For some unspecified reason the authors named Ranagol the Ram-headed Lord. Probably because the good guys (Pyarronites) think of him similar to Satan.
