This could be a double definition.

'are such enemies' is the first definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.

'cursed?' is the second definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

Can you help me to learn more?

(Other definitions for sworn that I've seen before include "promised" , "Given under oath" , "Stated on oath" , "confirmed in office" , "Affirmed" .)

I've seen this clue in the Evening Standard.
