Guess That Warrior Cat!

Riddle #4

Winner: @Jessie_WCFL
Correct Answer: Brightheart

~~~
My brother was not blood,
His eye far from me.
He took to the forest,
A land I could see.

As the moons went by,
My hunger began to rise.
Ana so came a spell,
And so came demise.

Once I was young,
Neglected and a fool.
If I could return,
And show them my rule.

But alas the battlefield of my heart is not here,
I slipped into darkness, a land with no fear.
This darkness would prove,
That I was never wrong.

A Clan without me,
A lyric with no song.
Beneath me was heat, above me was cloud, a family I wish not to see, and a tiger yet so loud...

Okay, that was long... And no, that was not my story thingamajigs, but the thing is, the longer the poem is, the more detail it has and you can guess really easily. Good luck!
