The truth behind Agrippa (and Alexander [spoilers]).

[Zoridium JackL]

just felt like pointing out hat the reason the shadow is chasing daniel is the he still has the orb, it left Agrippa because he didn't have the orb... if the shadow had the orb, i doubt it would have really cared what daniel did.

Except that Alexander took the orb from Daniel and brought it to his inner sanctum. Why didn't the shadow just pursue and kill Alexander? There were multiple points in the game where it was obvious that the shadow was going for Daniel specifically (example). Also, Daniel didn't carry it with him everywhere before he went to Brennenberg. He often left it at his house, I believe.

Once you touch the orb, you're cursed until you're dead.

firstly, that may just be because it is travelling in the same direction, and secondly, there are points in the game where you are litterally following a path the shadow has already taken, which means it has overtaken you at some point, meaning it isn't after youi, but something in the same direction.
