The clause is obscurely worded. Written so it is hard to follow.
He felt obscurely threatened. Indistinctly – he could not say why.

Obscurely or something else?

The mistake to watch for

Incorrect Correct
obscurly obscurely

The e is kept. Only whole, true and a handful of others drop it.

The verb is the busier word. Obscure as a verb – the fog obscured the view – is much more frequent than the adverb, and it means to hide rather than to be unclear. If you are reaching for obscurely in ordinary prose, vaguely is usually the word you want.

Frequently asked

Why is obscurely so rare?
Because the adjective and the verb cover most of the ground. English tends to say an obscure reference or the clouds obscured the moon rather than reaching for the adverb.
