Who?

But if they were powerful enough to capture the Horn of Fertility themselves, would they send someone to contact the Merlin Family to suggest a collaboration?

That would obviously be illogical...

After all, the relationship between the Merlin Family and the Watson Family was clear to all. From the 3rd Dynasty till now, it has been millennia of enmity.

Countless years ago, Lorr Merlin came out of the Ancestral Land and followed the old king to establish the Andlusa Kingdom. Only then did the declining Merlin Family take a turn for the better and slowly begin to grow. But during this time, the Watson Family didn't stop trying to suppress the Merlin Family. Only the two Ancestral Lands knew how many conflicts happened, both in the open and under the table.

This kind of rancor simply couldn't be defused.

If they had any other choice, how could the Watson Family give their rival a chance to get stronger?
