Help with Heart's Desire

I need Searing Enigmas to continue this storyline, and I have no idea where to find them or how to get them. Anyone have any insight on these things?

Every four weeks you can trade in four professional Perks (which you get from your profession) for a Trade Secret. One of the things you can do with a Trade Secret is “Something Else”, which gets you five Antique Mysteries and a Searing Enigma. There may be other, better ways to get them, but that’s how I tend to get mine.

If you have a ship, the orphan-court grind is probably the best way.

If you have money and supplies to burn, you can do the Chalcocite Pagoda expedition in the Forgotten Quarter multiple times to get Searing Enigmas without leaving London.

It has come to my attention that the orphan grind has been replaced with the Arbor grind. .

Thanks for the tips. I’ll use them.
