Fairy Tail, What is the light held in this hand?

The utopia drawn in your dream, don't let it end as one
There's something I want to tell my future self, who someday I'll meet

Sometimes the future is cruel, and can crack like a mirror
But we will be fine if we find it like no fragments were lost

Even if the frozen darkness stands in our path
We must never forget hope

Fairy Tail, what is the light held in this hand?
Because we're overflowing with the power of bond
We all know about the sorrowful tears
So don't ever surrender, don't ever sway
That's right, until we arrive to the dream we saw that day
