Yup! It was Raggedstar! You guys are awesome at guessing! Here's the next one:
In contrast to my fiery sister
I was the calm flow of water.
I had one path
And that was no mistake.
Yet, I never expected
All it to go awry.
Love doesn't belong to me
It shouldn't have.
Yet when I saw your gentle blue eyes
I saw your tragic love story
And how it became a new.
We were from different clans.
I couldn't be with you though..
Our kits were destined to be great
No matter what you saw
They were ours.
Our love was something forbidden
But, when I reach Starclan
I don't expect you to choose me.
But, I shall never forget our time together
My volatile crow.
