我现在将试着分析我们所知道的赤胆忠心魔咒的二种情形，先说第二个(我相信这个比较简单)。

I will now try to analyze each of the two situations of the Fidelius Charm that we know about, starting with the second (which I believe is less complicated).

我们大概有二十个人，这就大大削弱了赤胆忠心咒的力量。

And as there are around twenty of us, that greatly dilutes the power of the Fidelius Charm.

比如赤胆忠心咒，能够把一个人或一个地点完全隐藏起来以至于没有人可以找到他们除非保密人说出了他们的位置。

The Fidelius Charm, for example, can completely hide a person or a place in such a way that no one can find them unless they are given the location by a Secret Keeper.
