Minecraft mods are covering the tracks of a mysterious new villain! Gameknight999 reenters Minecraft to find it completely changed. Villages are larger than ever and more heavily fortified; life inside the game has become much more dangerous. Even Gameknight’s old friends are acting differently, and the changes are not for the better.  

Outside of Crafter’s village, a strange user named Entity303 is spotted with Weaver, a young NPC Gameknight knows from Minecraft’s past. He realizes that Weaver has somehow been kidnapped, and returning him to the correct time is the only way to fix things.  

The User-that-is-not-a-user races to catch Entity303 and rescue his friend, but they quickly disappear into a strange portal that leads to the Twilight Forest modded version of the game. How can there be mods here in the vanilla Minecraft? Just how dangerous is this new user to Minecraft, and what are his plans for Weaver? Only Gameknight999 will be able to find out.
