About Shadow

[Tanshaydar]

Of course spoilers!
Well, this is first time happening that I couldn't fully understand the plot after Silent Hill 1. I don't know if it's good or very good thing.

Anyway, at the end of the game, we see that the shadow was that fleshy thing. Well here my questions go:

- That shadow, fleshy thing, does it have a meaning in being that fleshy? We could pierce through it with some acid. It's not like it's from another dimension... erm, ok, it's from another dimension. I usually don't see fleshy things around.
- Are there Brutes or is there one single Brute? We saw a ripped Grunt, where we first encounter with Brute. I know Grunts are servant of Alexander, but Brute?
- Are Grunts and Brute(s) natural enemies?
- Who or what is the guardian of the orb? That fleshy thing or Brute?

Any help will be appreciated.
