Most half-elves after they were born are taught by their parents to hide their incredible power.

Because if they used it constantly, and their power becomes common knowledge,

It could easily lead to a chain of social incidents, that could prove to be fatal.

The countries on the continent have not normally taken this into much consideration,

And organizations that engages in in-depth physical examinations are very low in number as well as secretive.

Thanks to this, almost all half-elves hide their real identities, in order to maintain a peaceful life.

And due to their small numbers, they are unable to form any large country or organization of their own.

If any country or group were to discover their potential usefulness to military or civil affairs,

They would no longer be able to rely only on their own powers to protect themselves.

The Elves have not written any laws to protect the interests of half-elves,

Nor did they provide any instructions on how to treat these half-elves.

Strangely enough, humans tend to accept half-elves better than Elves do.
