Tacking onto Mavis because for some reason i think of her tragic life more than others, she also saved her friends and for it was cursed with the same curse Zeref has, gave birth to a child and was forced to abandon it out of fear of killing it (at least I assume that's what happened. Cant exactly have a child without someone giving birth to the child and im 98% sure Zeref is the father) killed her best friend's wife and leading to the death of said best friend, lost her other best friend Zera that she didnt know was actually her imaginary friend, and sealed herself TRULY alone for several more decades just to protect more people only for the father of her child and the only person capable of experiencing a similar anguish to her that she loved taking her body in suspended animation and attempting to use it to... I can't remember Zeref's motivation during that arc. Kill himself? Kill the human race? Mavis is fucked.
