(These people understand Undercommon without problem.)
The creature on the path freezes when you become visible. It looks about to see whether there are any more people about, warily turning its head one way or another. The creep on the left almost turns invisible withing the shadows, while the other fails to escape Sheiriya's senses. Apparently satisfied that you are all alone, the 'tracker' says in a hoarse voice:
"Actually, we are looking for a female like you, just a touch darker. But since she's not about, how about you staying and talking with me, will you?"
Now that Sheiriya can take a closer look, she sees that the chap is too tall for a drow and nigh fully covered in dark clothes. Dark eyes fix you, the few patches of skin that she can see are pale as the night's moon (if there were one, that is).
