How did the Ratri clan knew about the hideout if it's location was not known even to the demons, scouting drone owls or somebody snitched?
The queen is dead and so is nobility, they obviously don't know that yet, but offering of the children is pointless now.
Guess it's time to get back to Grace Field plantation, about time, they were too preoccupied with other matters and forgetting about the kids left in the premium plantations.
