The source of the dream/nightmare?
Ok I can’t get spoilers to work right
[spoiler=] Just missing the second bracket.
The only problem with your theory is the fact that there actually is no bloodstone very close by. The bloodstone that we know about within the maguuma is much further north in the Maguuma Wastes where, interestingly enough, a vast desert has claimed the jungle. Also, if you can claim it’s magic reaches from near the middle of the Maguuma Wastes all the way down to the grove, then your theory is also flawed because of the fact that the second tree is likely even closer to the bloodstone than this one because of the trajectory that we are shown for roughly where the second tree is
Personally, a theory has been forming in my mind that Nightmare is tied to mursaat magic (explained in detail in the Arah mursaat path, but in a nutshell they can phase out and “slip beneath the skin of Tyria” – as to what that actually means I have no idea (hopefully will do that path today).
It’s been said multiple times that it was the mursaat that had slain the people of Ronan’s village. It might be possible, that in their active use of that phase-changing magic, they influenced the area where the Plae Tree was going to be planted: both the victims who were killed by Spectral Agony and co. and the environment as well (they might have weakened the barriers between that “dimension” they hid in and Tyria. Now, what if the Dream is somewhere in that “dimension,” and the Nightmare is a sentient presence in that “dimension” that reacted to the invasion of the Pale Tree and the Dreamers in such an aggressive way?
Food for thought…
A fantasy of sci-fi cyborg implants grafted into the desiccated flesh of Guild Wars’ corpse.
Some of the Nightmare Courtiers that you can talk to doing a heart in the Caledon Forest say something along the lines of: “The Nightmare has always been. It is the dark thoughts and emotions that dwell within us all.” You must remember that the dream is, as stated by Trahearn (more or less, don’t know about that last one for sure, Memory, Aether, and Magic. the dream is full of memories, emotions and experiences from all sylvari,. The nightmare is just the dark part, the painful experiences, the dark thoughts and/or actions. But other than that, information is scarce, the dream is a mysterious thing indeed.
