Remember the Enemy

Hi! This is a Series I have recently started! I only have a chapter written, and a willing to accept characters, and chapters for the overall story line.

The Plot
Many adventurers are performing quests, but the quests are going out of control. All the villains all over Gielinor and other areas are becoming stronger, quicker and smarter. What could be going on, and why?

Prequel
Sandsire
