Aly organised and trained an intelligence service then used it to bring down a greatly feared and experienced spymaster and the monarchy in less than a year. ...I'm not sure what else I can say to add to that.

She's since acted as spymaster for the Copper Isles for six years. She's canonically good at languages and speaks several languages of her world plus Crow.

She also has tiny Immortal friends called darkings which are blots of blackness, quite intelligent and are able to listen and report to the darking she wears as a necklace (named Trick). In canon, Aly uses them as spies and communication devices. For FH, I try not to use them much, but they're certainly available and useful for a plot device if there's a way to make it logical.
