-The Sleeping Giant Mountain-
Waking the Titan will cause it to begin walking towards the Grand Scar. The path will lay waste to Slum Town, Slum Row, the southern parts of Durnmagon, and The Grand Arena. The Titan will make its way to the World Core where it will destroy the Lavos Remains and the World Core with it. Destroying the World and ending the game. Unless it is stopped before this.
-Durnmagon-
The Slum leader gives the party a quest to assassinate the Grand Leader. If the Party Succeeds and Magon becomes Grand Leader, she will quickly lead the world to ruin(Unless the party has already Saved the world or previously killed the Lavos Remains). The Grand Leader knows the secret of the Magical Spring and killing her will shut off this source of water. The Grand Leader also is the only one in control of the Grand Arena's robotic guard and sentries. Her death will create an immediate robot uprising.
-Valley of the Clouds-
An ancient entity dwells in the mysterious and ever present fog of this curse forest. The entity feeds off and steals intelligence and memories of those it feeds on. In ancient times this entity was revered and worshipped as a god, as such, it still believes itself a diety and craves worship. If this entity becomes powerful enough, it can begin to assert its dominance once again. (If Lavos Remains are defeated, this entity will begin to weaken.)
-The Floating Forest-
Outlined in Hidden Lore. A player can take control of all magic on this world. Having the Sword of Mana will make defeating Lavos Remains significantly easier. Those living on the world will fall into chaos if the Mana Tree is destroyed. The Grand Arena will fall, however, the native Scavs and much of the Slumlands will eventually recover and begin to prosper without access to magic.
