OK, I talked to Brandon about the chart. He says that in the typical chaos of a signing, he didn't notice that the circles that were being pointed to sometimes weren't the ones he thought they were.
Anyway here is what I have to say about the chart:
Gravity and Pressure should be switched. The "surface tension" one should be switched with the unrevealed one next to it.
Also, the in-world names for many of the Surges haven't yet been canonically revealed and may not ultimately match what's here. For example, where it says light, on my chart I have Illumination.
The names of the Heralds are also a hodgepodge. Some of them are the ancient name, some are the Vorin name, and some are just the name of the number that corresponds to that Herald.
