I swore it cannot come to this
the day we say goodbye
the day we watch the stars fade and the sun die

I swear I will not see the day
You quietly pass by
By things will get brighter
If you stay right by my side

Luna, dear, we love you come back
This is from the warrior cats forums
I wish you inflict no harm on yourself
or I will fade in tears
