I thought the WoB was the opposite, that they'd be interested much more in the field agents.

What would it take for a member of the Seventeenth Shard Shard to convert over to a member of the Ghostbloods?
Brandon Sanderson
Oh, the Ghostbloods would actively recruit from them. So, I think it would not be terribly difficult. It 's gonna depend on which kind of Seventeenth Sharder. Because there are a lot of non-field-agent Seventeenth Sharders, which would be less interesting. Field agents, they would actively recruit.
