After a few weeks of intense battle for some reason Ren's men suddenly retreated. The allied kingdoms' forces were confused but they still did not let their guard down. Even though the enemy army retreated they did not advance but instead tightened their defenses. The allied Kingdoms knew that the only reason they were winning was that they were defending, if they make a mistake now and start an offensive they might be annihilated. So they continued to stay within their borders.
...
It was during a rainy day when the allied kingdoms' forces received intel that five people from Ren's side were approaching their borders. It has been a while since any from Ren's side came to them. It was quite curious as to why they picked today to attack.
