What does 事実だけがでんと構えてる mean? My breakdown of this sentence is, although I'm sure it's wrong:
事実だけが = the fact is
でんと = formally/officially
構えてる = start something/ establish something
So the sentence translated is: The fact of the matter is, something was established. Is this correct? I think there could be some nuance I'm missing though.
The でん(と) is an onomatopoeia for (the subject presenting itself) grand or big.
構える here means ある態度をとる or simply to exist.
The linked entries have relevant examples:
彼はでんと構えて動こうともしなかった
He had 「planted himself in the chair [《口》 plunked himself down very firmly] and showed no sign of moving.
部屋には大きな机がでんと置いてあった
A big desk was placed ostentatiously [conspicuously] in the room.
いかにも[大家]{たいか}らしく構えている
He has the bearing [air] of an important person.
So the sentence in the question means literally The fact alone is there firmly. (I guess this is not a good translation, but makes sense in the context.)
