If you were to design...

I'd like to be able to use the time machine in helios tower to go into the future to victoria island, but here's the catch: It's been overrun with monsters. Some powerful being in the past has destroyed the protection over the towns from the monsters, and the only safe places are in the job instructor areas, where there are also all the store NPCs. The monsters are also stronger than their past counterparts because of this evil being.
