While Poseidon seems to have a ton of children with other immortals, he doesn’t appear to have had many children with mortals in the last century or so.

It is stated in “The Lightning Thief” that Percy is the first son of Poseidon to ever be at Camp Half-Blood, and we know that Camp Half-Blood has been around since the American Civil War.

It is stated in “The Son of Neptune” that Camp Jupiter hadn’t had a child of Neptune since 1906.

However, we do know that there was at least one son of Poseidon who fought in WWII.

Now, there could have been daughters of Poseidon at Camp Half-Blood, and it never actually says that the sons of Poseidon that fought in WWII were half-bloods.

There is also the possibility that there might be demigod camps in Europe.

All of that being said. From the known evidence, Poseidon doesn’t seem to have been having a lot of demigods even before the pact at the end of WWII.

Thoughts on this?
