What is the meaning of なりうるがため in this context?


> 恐るべき 事態に なりうるがため、 子細を 伝えることはできぬ。

The context is that I'm talking to a wizard in the game who happens to know
something about my future.

Currently, I am trying to figure the exact construction/meaning of なりうるがため and
so I far can guess that the sentence means something like I can't tell you the
circumstances of your future, otherwise an awful event might happen.

But I can't wrap my head around what なりうるがため exactly is in it's construction.




なりうる is just a compound of なる "become" + 得{う}る "to be possible".

〜がため（に） is an archaic expression meaning "for the reason of X". が in Classical
Japanese had a possessive sense (similar to の in the modern language). The
normal translation into Japanese of the title of Hemingway's book "For Whom
The Bell Tolls" is
[誰{た}がために鐘は鳴る](https://ja.wikipedia.org/wiki/%E8%AA%B0%E3%81%8C%E3%81%9F%E3%82%81%E3%81%AB%E9%90%98%E3%81%AF%E9%B3%B4%E3%82%8B),
showing the same construction.

So the meaning of 恐るべき事態になりうるがため is "since it could lead to a frightful
situation", with an archaic nuance. This nuance would certainly fit with the
character of a wizard making a portentous announcement.
