you...were...our friend.

This picture have a lot of meanings here.
----

the stars on the sky
 mostly the meaning, that the 'You' is not from there, was in fact, never from there, the 'you' was from a place beyond we know.

 The gray forest...what once used to be green, what used to be welcoming, is now blank, cold, empty, dead...grey.
----

 the words, saying clearly the main focus;
 'what once used to be...'
 But now
 It no longer is.
----

You...
the one we see, the one we trust
the one we met and got to talk and know
the reason...the responsible.
---

Were...
from one to another
from one plain to another
from good to bad
from light to darkness
from life to death...
It's the transition, of what once was
Defining the face of the ones from the past, linking towards the bitter future they now are.

Our Friend...
 the tree, from the one that was once 'our friend'
 although no longer 'our friend'
 it is still there, healthy and alive
 however
 it's branches
 once for shelter from the rain, the extreme heat...Once a place for peace and rest...
 Now is a prison...now is the thing that gives you misery, the thing that bitterly sealed 'our' fate.
 once protected by those arms...now enslaved by it.

EDIT: refined some things and made the 'were' move visible.
