Gemhearts and the Sibling

[Confused Honorspren]

Roshar is “a created planet” in a system “manufactured for a specific purpose.” I hypothesize Roshar’s purpose requires its three Great spren to grow the planet faster than is normally possible.

• The Stormfather (nee Rider of Storms) energizes growth with Stormlight.
• The Nightwatcher manifests growth by using Stormlight to transform spren from their Cognitive to their Physical Realm aspect.
• The Sibling IMO supports and enhances animal growth through gemhearts.

Singers need three things for their transformational life cycle: Stormlight, spren, and a gemheart. I hypothesize each Great spren personifies Singer pre-Shattering perception of these three necessities.

The Stormfather and Nightwatcher are the source of Stormlight and spren (IMO). Stormlight enables a spren to enter a gemheart and manifest in the Physical Realm as a Singer form. The spren Connects to the Singer’s Spiritual aspect through the Singer’s gemheart. This Singer mechanic predates the Shattering.

Almost all Roshar’s creatures have “some sort of gemheart.” Gemhearts are composed of Investiture leaked into the Physical Realm. Gemhearts allow spren to enhance Greatshells, skyeels, and Rhyshadium. Most Rosharan gemstones are made from gemhearts, but some gemstones occur naturally.

I propose the Sibling is the source of gemhearts. IMO, the gemstone-encrusted pillar in Urithiru’s basement IS the Sibling, or at least its Physical Realm manifestation. Renarin tells Navani’s scribes, “They’re not fabrials. They’re a fabrial.” (OB, Chapter 44, Kindle p. 455.) I think Renarin makes two points: (1) the Sibling is non-binary (“they” is singular), and (2) the pillar is the Great spren inside the Urithiru fabrial. Kalami’s team fails “to infuse the gemstone pillar.” (OB, Chapter 44, Kindle p. 454.) The pillar remains inert – “slumbering.”

I agree with those who believe the Sibling is the Spren of Stone. I think the Spren of Stone personifies the Rosharan continent after Adonalsium built it through fractal mathematics principles.

I speculate Autonomy’s Patji Avatar built the Pantheon the same way.

I think fractals are Autonomy’s “primal force.” Gemstones are fractals. Brandon says Autonomy’s assigned Investiture sits on Roshar. I believe the Spren of Stone is a potential Autonomy Avatar. Many disagree. If I’m right, it would explain why the Stormfather calls the Sibling “they” and Brandon hints the Sibling is non-binary: Autonomy too is non-binary.

It makes sense to me each Great spren personifies a different aspect of the Singer life cycle. Singers first personified the Great spren. It also makes sense that Great spren Investiture comes from three different Shards – and Odium is not one of them.

@RShara and others feel Brandon wouldn’t introduce a fourth Shard into SLA, mostly for narrative reasons. Two answers: First, Autonomy may not have an active or on-screen role. That Shard may only become Roshar-relevant later in the cosmere story and maybe never. Second, I feel Brandon does foreshadow Autonomy on Roshar. He specifically mentions Autonomy’s Rosharan Investiture in a WoB about the Patji Avatar. Brandon inserts this tidbit without any context, as if he were glad to drop an obscure breadcrumb.

Regardless of the Sibling’s composition, they do seem associated with gemhearts. The fabrial magic system needs both spren and gemstones, plus human design. Fabrials to me are an Autonomy-Cultivation combo system, fronted by the Sibling and Nightwatcher.

I have to say, I really like this.

I'm not so sure about the autonomy bit, but it could work.

Agreed.  Odium says only three shards that need concern you and while trusting him is usually a bad idea I think in this case he was being honest.
