This is a little makeshift poem battle.
Zeref:
Through centuries of events,
I no longer know my own intent.
Through fires blazing the lands,
scorched are my own hands.
If I could turn back and start anew,
I would end this world before...
its evil it could turn to.
Mavis:
You have seen pain and misfortune,
and yet you refrain from taking action.
You believe to be an observer the best path,
as you sit back and the world falls in its wrath.
In my fraction of time upon this dimension,
your downfall is much to glaring to even mention.
Know your mistakes as your own child,
Leave the rest to me as your actions are riled.
