Are They All Siblings?

Denth, shashara, arstil and yestil refer to themselves as siblings. Does this mean they have knowledge from when they were alive? Do it mean that vasher is the only scholar who doesn't? What a wonderful question. Guess what, rapho, you're supposed to be asking these questions about the scholars. And poor, poor vasher. Again. Sonfonly that, and the didn't even think about that. It makes a lot of sense though, if vasher was always on the outs,. Not just because of theas itt rando, who yet doesn't have his sibling.
