Sacrifice [6]

Within 10 years of the elves' arrival in the 3000 Beast Mountain Range, Alaric erected the Myriad Illusion Veil to protect them from outside forces and the ongoing war.

And due to his protection, the elven race was able to gain footing in the mountain range without being killed off by the beasts around them.

Over time, their population boomed and they experienced prosperity. Those who remembered the origin of their city became few and far between. 

The final 10,000 years played out in front of Damien's eyes, but he was hardly paying attention. His mind was completely focused elsewhere.

Just now, due to Alaric manipulating the memories for Damien to safely digest, he was able to experience 100,000 years without actually experiencing 100,000 years.
