Honorless

Truthwatchers and Lightweavers share the Surge of Illumination. In Oathbringer, Renarin had been having trouble using the Surge of Illumination to craft illusions like Shallan does. While Shallan is a standard Lightweaver, Renarin is not a standard Truthwatcher as his spren is Corrupted, that makes comparisons difficult. We do, however, have another example of potential usage of Illumination by Renarin. In the Battle of Thaylen City, Renarin uses light to banish a Thunderclast. I don't think this is specific to Renarin's unique condition as, like Glys, Ym's spren too told their Radiant that they could make things go away with light when Nale attacked him in WoR. We do know that the Surges have a Spiritual component to them. Shallan using Connection to those she draws for her Lightweaving. Renarin glimpsing into a person's Spiritual and applying it on the Physical body. Both Illumination and Progression have a Spiritual element within them. Perhaps Truthwatchers are more proficient in Spiritual manifestation of their Surges, like the Bondsmiths. We do know that the Surges don't always manifest in the same manner among the Orders that share them. Perhaps this is how the Surge of Illumination manifests in Truthwatchers. Maybe they don't craft illusions. Truthwatchers are more about truth than lies, which are under the purview of the Lightweavers. Alternatively, the banishing light could also be a combination of the Surges of Illumination and Progression, their Resonance perhaps, a cleansing light (might as well go full throttle on that paladin theme)

I think of it as similar mechanics Also, excuse me as I borrow the title format

Could be, that's another popular theory

We do have confirmation that Shallan uses Spiritual Connection when she sketches people, Pattern also refers to inspiring others as transforming them in WoR. She isn't using the Surge of Transformation on them, just convincing them that they can change with the aid from their idealized Spiritual perfect self.

Did you have to phrase it like that?

Some people theorize that the Sibling might be the spren of stone

Welcome to the Shard!

First Dreams is Kaza's ship, Wandersail is Rysn's ship that she was gifted by her Babsk

I think of what you described as a Spiritual manifestation of the Lightweaver Surges, like Dalinar's use of Spiritual Adhesion. I think some Orders were just better or worse at it, just like they are at one Surge or the other.

Welcome to our little corner of the internet

He's called Truthless because he claimed that the Voidbringers were returning. Truthless is part of Shin culture. Being Truthless meant Szeth had to obey anyone who had his oathstone. It's why he's so angry at the Shin leaders that his Ideal of Crusade was sworn against them.

He was looking into Hemalurgy with Spook and there's also Southern Scadrian tech, which was apparently taught to them by him. A lot happened after the end of the ash.

Then it makes me think Autonomy

Oh yeah, I was wondering why Lopen would be there with Rysn, I forgot he's a Radiant now for a sec there. I'm also disappointed that sailor spren don't exist, also I thought that was Cusicesh for a sec. Heck, the "different familiar character" and being tied up and this novella being about Aimia, I thought it was Axies the Collector for a sec.

I have to say, I did not see that coming! I was expecting the prologue to take place on the deck of the Wandersail. It's nice to have confirmation that Yalb survived. Shallan saw Yalb surviving in WoR somehow, I think it's Shallan's ability to form Connections with those she draws (capital-C Connection, as confirmed by Pattern in the Battle of Thaylen City) could be something that the Lightweavers share with the Truthwatchers, they are supposed to be able to see something. Extracts from WoR, pasted from over on the Discord server:

Kaza's, I think. She was an interlude character in Oathbringer. The Soulcaster who was killed by one of the Sleepless.

The Blessings of all fantasy gods be upon you!

Well... there is the Iriali religion of the One, that might shed some light on it

The spren seem to know of the truth regarding Aharietiam, they seem to know that the Heralds abandoned the Oathpact. It stands to reason that they might recognize the Heralds. Could the spren detect Honorblades or able to differentiate between Shardblades & Honorblades? Syl does talk about Szeth's Honorblade and how he's not bound by oaths in WoK but I also seem to recall Dalinar worrying about someone with an Honorblade pretending to be a Radiant in OB

One of the two Surges available to her Order of the Knights Radiant is called Progression. It can be used for healing (Regrowth), we've also seen her use it to facilitate the growth of plants (when she climbs into the Skybreakers' Tashikk hq via a window)

No, Wax & co mistook the Sovereign's identity

Lifespren are attracted to flora, it's probably the vines.

Presumably yes. So far, Shin animals that the other Rosharans find weird have been Earth animals.

Have you completed Oathbringer? The Stormfather casually does drop that bombshell on Dalinar after he sends his requests to form a coalition to the monarchs of Roshar. He's Ishar, the patron Herald of the Bondsmiths.
