You've killed us both

[senataur]

I always took it that the 'red goo' was a consequence of whatever Alexander was up to in the castle. From the beginning before I knew anything at all about what was going on.

In the chase sequences I never thought it was the shadow that was chasing me. The first chase was a water lurker, the second I thought was a normal monster and I didn't turn around for the third.

If you continue with my line of thinking, the red goo could just be the result of the ritual Alexander was performing. In the 2 endings where the ritual is completed and the portal appears and either Agrippa of Alexander goes through it, the red goo takes over and kills anyone left over in the Castle.

In the ending where Daniel stops the ritual the red goo is also stopped.

Has anyone got any information that would counter my thinking? Is the shadow actually the red goo?
