You've killed us both

[thePyro13]

Daniel 'used' the orb just by touching it. The shadow chases him because he isn't powerful enough/doesn't know how to use it.

Like I said, I think the shadow didn't chase Alexander because he knew how to use the orb properly.

But Alexander get this knowledge from Agrippa. We all know that Agrippa knows ALOT about Orbs. Definitely, he KNOWS how it works and how to use it, but! The Shadow -- as you says -- chased him, that means he doesn't. WTF.
Do you see magic light of pure logic here? I do not.

Nope, still can't see.

Tho, this could explain why the second Shadow didn't chase Daniel for touching Agrippa's Orb. Since he got used to Orb's affection and now KNOW it well - he was able not just assemble it, but do it in right way and avoid attracting another Guardian.

One of the notes written by Alexander speak of him wanting to return to the other side. Agrippa had never made it through the portal. Only Weyer and apparently Alexander. It's possible(maybe implied by the portrait of cthulhu Alexander) that Alexander originates from the other side of the portal in the first place. He talks of being banished from there.

Aprigga and Weyer are on the other side of the portal. Who knows what's over there, it could be an immaterial realm. Weyer is capable of travelling through the cosmos with the orbs he possesses(as claimed by Agrippa), who knows what he is capable of. That and the fact that you(the player) are overhearing this conversation might suggest that Daniel is not quite dead yet. And may still be saved. In such a way similar to the fact the Agrippa was just a head, and yet has clearly survived.

Exactly what I meant: pure speculation and theories. Everyone can make up his own story here. Weyer is A merlin just in different body and different name, etc, etc

Yeah. Most of the stuff in amnesia is like that, these are all just possibilities after all. Though I find it fun to try and dissect the small information that we have to figure out what some of the less solid clues could be referring to.

The shadow killed him because Daniel felt that he was the source of all his guilt.

Now that's funny. Since when Shadow is a Daniel's dog?

Based on my earlier assertion of the Shadows behaviour being related to Daniels sense of guilt. The above behaviour would make sense.

Otherwise, who knows?
