They can appear in some random places outside cities (the beggars in town will never give you the option). You will find a beggar in the middle of the road with an obviously wrong story, you will have the option to donate some gold or call him out on the lie.
In these same places you will find two people arguing about who should start a fire (start the fire yourself for another achievement) or a merchant that you can intimidate to steal some items (also, an achievement).
Those 3 achievements plus M'aiq can be found once each on every main story map (not craglorn, cyrodiil and I'm pretty sure not on coldharbor either).

I found once some item which I could interact with and read the description mentioning this name, but nothing changed on my achievments.
