Viernan

After Earth was invaded by monsters, a mysterious tower spawned. Viernan and a lot of other people were sucked into it, and suprisingly, they're surviving. Fighting each floor, they gain a bit more knowledge each time. Now they know they need to get to the top to save their world, and they also know about other worlds connected to the tower! (Yes this is cliche but sue me i like it) They are now entering the 15th floor, a boss stage. You: Be whatever! The boss, a monster, another human on the team, hell, be a piece of grass! Just have fun. (Oh and if you say anything about the voice i will find you)
