This is probably not a "Twilight camp" and more likely the dwarven shaman training area in Stormwind.

Very interesting (and inherently awesome, of course).. I'm hoping we will actually get to learn something about the Old Gods this time around, similar to how we discovered the Titan story in Wrath. Because other than being big ugly manipulative blobs, we actually have no idea what their gameplan really is, or what all those Forgotten Ones and other creeps are.

*edit* Right, I already speculated about Titans as temporary enemies.

Un-influenced Titans and their underlings as situational enemies would definitely be interesting. I don't think whether you can paint anything Old-God-related as "good", though. If they do manage to pull that off in a good fashion, Titans and Old Gods would remind me (even more) of the Cosmocrats and Chaotarchs of the Perry Rhodan SciFi series.

Since the series is probably not very known, I'll explain "shortly":
When they were introduced, the Cosmocrats came off as positive god-like beings, three steps of evolution above spacefaring species, with a rather symbiotic connection to those lesser beings, trying to bring order and life to the universe(s) - the aesthetic albeit emotionless Algalon is like a direct copy of their robot messengers/representants, sterile and perfect, though some have helped humankind apparently without their masters' knowledge or approval.
The Chaotarchs were their negative counterparts, evolved in parasitic way, feeding off the lesser beings, consuming their home galaxies in the process. Their ultimate goal seems to be ending all universes in a heat death, in "chaos", absolute disorder, in opposition to a feared standstill by the absolute order that the Cosmocrats would bring. This may be propaganda or a metaphor, though humans encountered one parallel universe where the Chaotarchs apparently had accelerated the heat death.
One major tool for their goals are the negaspheres: initially small malignant growths (from our POV) in time&space that would not last very long on their own as the universe has self-repair mechanisms, these tumors are protected and artificially advanced to grow, to a stage where it includes one or more galaxies - "normal" physics of the respective universe are perverted to create something strange, changing some life forms to creatures adapted to these new physics, and killing off everything else, whatever survives the infestation of its planet soon is purged by "natural selection". Very reminiscent of the Old Gods' corruption.

It later became apparent, however, that the Cosmocrats lost track, while they weren't actively harming lesser beings, they saw them as mere tools to achieve their goals, easy to sacrifice in large masses, and programs to promote the spread of life were cancelled as "Life Itself" as in the mortal species became a too large factor, while recent information show certain altruistic albeit most likely propagandistic features in Chaos organisations, at least they showed interest in their underlings - while they were still enemies of the humans and their allies, they sometimes appeared to have more in common with them than the Cosmocrats.
Overall, the authors took their initial concept of black and white created in the late 70s, at the height of the Cold War, and added the modern gray: everything can be "good" or "bad" in context, which is very strong in Warcraft, too, at least since the third RTS.

Heh, now that was an exchange. I wouldn't be surprised if the Horde ended up in a civil war by the time the last content patch of the Cataclysm content-cycle rolled around. Openly threatening assassination is very interesting though.
