Legend
Yes, the Kraken Society is specific to the FR. It's been around since 1988 or thereabouts.Aren't Krakens in 5e linked to the Kraken Society and isn't the Kraken Society FR lore?
I'm pretty sure it's just the one kraken, Slarkrethel, who founded and secretly runs the organization. Slarkrethel (and the Kraken Society) most recently appeared as secondary antagonists in Storm King's Thunder.Some Krakens are connected to the Kraken Society, but even with FR its not all of them.
