Resurrection as a Template for flavor.

[Helix7901]

First of all, i will try to situate you in the aspects of my campaign and my character, so you guys can better aid me in my question. If you are not interested in reading a lot of stuff from my game, just don't read the "spoiler" box and go to the direct question below...

read if you want:

The campaign that I'm currently playing is set in a low-magic scenario very unique and original created by my GM. This world has a more limited approach of planes and magic, so resurrection is not something mundane. Having said that, my current character has recently died (in a very heroic manner btw), and I would be fine with it, if wasn't for the fact that he is of great importance for the current events of the campaign lore. By this reason, my GM decided that instead of just making a new character, my old character would be resurrected somehow.
The thing is, in this world, resurrection plain and simple is something that simply doesn't exist. And only through means similar to undeath would my character be able to return. This put me and my GM to the search of a template that would fit to the characters resurrection.
My character was a Neutral/Good Ranger inspired by Strider, Aragorn alias in the first time the Hobbits of LotR encounter him. That and the hole vibe of the Rangers of Middle Earth was my inspiration to this character, so the Lich and Death Knight templates doesn't really fit him.
Then today when I started looking for a good fit I remembered the new LotR game that has been announced and remembered the means of the protagonist (a Ranger) resurrection as a Human possessed by a Wraith. That would be perfect for my character, but i still don't know the best template to fit this kind of character, nor if it even exist.

So my direct question is, What template do you think would fit better a Ranger resurrected by spectral means, in a way similar to Thalion, the protagonist of the next LotR game??

I was thinking of the Shadow Creature template, and even considered the Demon Possessed Creature (though I am declined by the fact that the Shadow Demon is not covered by this template), since this seem to fit better in the flavour of the character. What do you think??

So... Anyone?
I just wanted to know if anyone knows of a template, or something as such, that fit the spiritual resurrection theme.
I guess that me and my GM will have to decide for ourselves.

Too bad, cus this looked so cool...
