Aha. There might not be physical evidence left behind by the Heavengate, though there might. You'd be surprised how good scientists are good are finding physical evidence left behind by phenomena. There might be some induced radioactivity or all the clay pots in the area have their structures aligned with a magnetic field caused by the portal (this is a real technique!) because they were nearby when they were baked. Who knows? It's worth investigation. After all, it WAS the only known portal to Heaven that wasn't completely owned and operated by Heaven.
Even so, there is still other things that can be done. After all Baldricks spent all their eternity guarding the thing, sitting down the support staff of the Heavengate and interviewing them would be a good start. Talking to people like Luga is good, but finding some high unholy muckity mucks in the Naga and Gorgon communities would be even better. Try to weed details out of them about the daily goings on; if there is maintence, if there are regular specific visitors, et cetera. Hell Gates Alpha and Beta don't seem to have support staff Baldricks keeping them open, they just seem to be. Did the Heavengate? Were there a coven of Naga always on staff there doing weird shit that the Baldricks guards learned to carefully steer clear off? Did they have any magical instruments?
Once you get a mound of voodoo woodoo bullshit from the Baldricks, start sifting it for facts and consistancies that reveal the gems in what made the Heavengate special.
That is an interesting analogy. If you would assume the energy is like way water would flow... That makes me wonder if the Heaven-Hell-Gate was self-sustaining or needed regularly new energy.
Keep in mind all analogies are suspect. I happen to LIKE the PES Mountain/Valley analogy, because I have a special place in my heart for spectroscopy and physical chemistry, in addition to it seeming to fit the facts that have been presented. If we go with it and call the Heaven-to-Hell Portal forbidden by Portal Selection Rules, then it stands to reason that a good way to go is to figure out what is queering the system to make the portal possible.
