hint from the developers about the Academy
It's like a hint from the developers about sulfur because of Sulfur Week. In other words, it’s something like a joke.
I read info about Raelag and came to the conclusion that there will be dwarves in "Shades of Darkness"
They definitely won't be a full-fledged faction. Because things like the number of factions are announced initially. I remember many fans were expecting an unexpected surprise in the form of a supposed 6th faction for the original edition. But, as expected, it turned out as promised – five.
It is far from certain that the plot of the expansion will describe what is said in Raelag's biography.
