[OB] Surgebinders as WMDs

[Stark he/him]

We heard hints from a few spren sources, and from the translation of the Eile Steele that Humans came to Roshar after as refugees after destroying their own world, likely Braize.  We have hint that they did not shatter the planet, but they 'scorched the earth' in some fashion as to make the surface uninhabitable, forcing them to take to the sky.  But the planet itself is still there, capable of sustaining an atmosphere, as seen:

Spoiler

In the AU map.  Both Braize and Ashyn are still there.  Whichever humans came from, it is still there.  And if it could hold an atmosphere before they ruined everything, it can hold an atmosphere after.

I am shaky as to whether humanity had access to the surges before the Nahel bond, which we know came after a number of Desolations, to imitate the Heralds.  But whether pre-Roshar humans were capable of surges or not, somehow they destroyed their world.

We saw in WoR, that enough binders working in concert were able to bring the Everstorm into being, though admittedly, these were Voidbindings.

So what would each Order be able to do, working in concert, to create a significant enough event to be considered Natural disaster or extinction level events?  This is not using Dlainar's Stormlight supercharge, but potentially done at the height of a highstorm for the limitless Investiture temporarily flying around.I don't think all orders are capable of causing extinction level events, but here are my thoughts, please add your own:

Bondsmith (Tension and Adhesion): On their own, not much.  These guys are the Blue Lanterns of Roshar - they can supercharge the other orders, like Shallan's map.  

Windrunner (Adhesion and Gravitation): I don't have much for this group, but I could see them using gravitation to create a singularity.  Numerous lashings all pulling inward, focused on a single point.  Or lashing things together with adhesion and in separate directions with gravitation to tear them apart.  Create hurricanes?

Skybreaker (Gravitation and Division): With enough stormlight and Skybreakers working together, they could replicate Ultron's plan from the MCU, splitting off a chunk of the planet with division, and lifting it with gravitation, to meteor drop it on the planet.

Dustbringer (Division and Abrasion): With the ability to divide and control friction, this order could trigger all kids of natural disaster, from earthquakes and tsunamis to volcanoes.  They could split the crust of the planet down to the mantle, and possible rend the world in two, with enough power to manipulate.

Edgedancer (Abrasion and Progression): I feel like something sinister, along the lines of Poison Ivy style venomous plants take over the world could come from Edgedancers, but I don't have much else.

Truthwatcher (Progression and Illumination): Similar to Edgedancers, I don't have much for this group.

Lightweaver (Illumination and Transformation): Any targeted Soulcasting could cause no shortage of issues, but can't think of specific examples.  Maybe large scale soulcasting on the stone-to-air or air-to-stone spectrums to create concussive vaccuum's or explosive air releases?  Mass creation of highly flammable, low flashpoint materials, like hexanes, or reactive metals like cesium? 

Elsecaller (Transformation and Transportation): Soulcast nuclear material and transport it to create nuclear blasts?.

Willshaper (Transportation and Cohesion): Don't really know enough about these surges to theorize about what disasters they could cause.

Stoneward (Cohesion and Tension): They can melt mountains.  Create mud slides, volcanoes. Massive waves even.

 

SO, what do you guys think?  How do you think various orders could destroy the world as the spren fear?  And more importantly, where am I wrong about the powers or science available?

I wonder if the oaths prevent a WMD type situation that happened on humans previous home world (I think the main theory that its Ashyn not Braize). Although one example of extreme destruction on Roshar that might have been caused by surgebinders is the shattered plains. Not quite world ending but it seems like what ever created the shattered plains pretty much destroyed what was Natanatan. If I had guess the shattered planes where causes by Division/Abrasion or Gravitation/Division but who knows, since we have barely seen division on page.
