Space Occultism & Sacrifice

So reading about elemental metaphysics on Scrap Princess' blog and she mentioned this:

Tribute is anything people care about, the elementals don't really care what is exactly, they just care that you care about. There's a certain amount of potency they gain from it but it's more for display of status to other Elementals and status corresponds to territory and lobbying power

Which made me think of some stuff from the Chaos Magic blog Runesoup. Here's some of what Gordon White (the blog's author) said in Sacrifice And Its Discontents: An Extradimensional Exchange Mechanism:

What Ian said was that the spirits are fascinated when we deny ourselves something.

Brain sparklers again. Because, like consequences, a lack of something is difficult to experience in the non-physical. I put it to you that these two observations are intimately related and simply describe different parts of one continuous spectrum.

If Ian is correct, and his experience appears to match my own, then in cases of sacrifice, the non-physical recipients are fed not by the things they accrue, but by the things we deny ourselves.

So what would spirits in the darkness of space (Void elementals?) want you to give up? Air? Heat? Gravity?

I could see ships doubling as temples with low heat (so low Fire) and low Air in order to gain favor from spirits. This favor might result in skewing probabilities - from my initial reading of the Coriolis RPG this is something that happens with worship of the Icons. As noted in the article even building a ship dedicated to them would please the spirits, because it is giving up materials and time that could have gone into something else.

But if it is an "extradimensional exchange" mechanism, it also means that there is an opening somewhere between us and the spirits sustained by our sacrifice. Yet it seems this opening is not in the material world, but in the mind. This might be how Divination spells are powered then...
