Rosharan antigravity

So, would the fabrial for this use gravitationspren? I assume so.

I imagine that this would instead be some kind of combo between unkeyed metal minds and windrunning.

Also, I'm under the impression that the type of spren is only one of many factors, and metals, shape, and type of gemstones are more important. It feels like it also might be used with some gyroscope-esque device and something similar to the way spanreeds work, with the rubies.

curious, did you hear this somewhere, or just an idea that popped into your head?

Just an idea. I mean, flamespren are in heating fabrials.

good point. I imagine there's multiple ways to create it and using gravitation spren is one of them. It depends on what is the easiest to create, and your idea is likely more plausible. I thought it was a quote from TSM or IED, and so immediately started theorizing connections. Also I was moderately wrong, cut and gem type affect which spren you can attract, not the function of the gem directly. very plausible that you're right.

The "cage" would be important too.

Quote

"With a captured spren, you may begin designing a proper fabrial. It is a closely guarded secret of artifabrians that spren, when trapped, respond to different types of metals in different ways. A wire housing for the fabrial, called a “cage,” is essential to controlling the device." -RoW Chapter 6

For example, the cages of heating fabrials are constructed from Pewter because applying Pewter to a gemstone containing a spren amplifies certain aspects of that spren's nature.

My guess is an anti-gravity fabrial would use a gravitationspren and a Tin cage (Tin has the opposite effect of Pewter - it diminishes attributes associated with the spren). Painrials are made from Tin and Painspren, for example.

You might not be as wrong as you think. The gems found in the Urithiru gem archive were cut specially so that they vibrated in specific patterns when infused with Stormlight. In this instance, they were used for encoded messages. But I wouldn't be surprised if this could have some kind of fabrial-adjacent usage. You could create a CD-player of sorts where specially cut gems are the 'CDs' (or CG's I suppose). Being able to encode data like this could also be important to very high-tech fabrials in the far future of the Cosmere.

I forgot about the cages- good point!

Its also possible that Rosharan Antigravity is a new kind of surge fabriall, utilising the surge of Gravitation. We know that Transformation, Transportation and Progression Fabrials exist, (Soul Caster, Oathgate and Regrowth Fabrial) so I dont think its a stretch to say that other surge fabrials would be possible.

[Adonalsium Will Return He/him]

@Wahrheitswächter- a surge fabrial is possible, too. I didn’t think of that. However, it is written, can’t remember where, that surge fabrials require a spren, and I feel like that wouldn’t be mass produced.
