Liquid dust, from what I believe, doesn't 'run' into Necrovion (at least not naturally). Rather, the Howling Gates serves as a human-based 'filter'--and possibly also a mirror, though the mirror is likely bigger than the gates... The 'mirror' is more metaphorical than literal. It is the 'balance' talked about in the adventure log. As heat is created by actions, liquid dust, which is related in some way to potential, is also created. This is more of a philosophical concept than anything, imo.
Here's the example I gave in the chat:
If you have a car, and choose not to take the action of driving it, then no potential of where you can go is created/released. Basically, you can only potentially go places with the car if you drive it. If you don't drive it, you can go nowhere. It could also be compared to a candle. Light a candle and it makes heat, but it also creates many shadows.
Thus, if you take an action, heat is generated, and also potential (related to liquid dust). If you take no action, no heat and no potential is released/created.
As for there being some kind of 'solvent' that doesn't exist in Necrovion, would you explain that further, Dark Demon? Not sure what you're getting at with that...
