[@my Lalia] Alright, what about this darkness that they are in? Is this plain old regular darkness, or is there something special about it? 

In other words, how would it affect Tamara's thermal vision?

Also, is there just one, or more?

It's a "special darkness" and Tamara's thermal vision won't be able to pick up those attacking them. She will be able to see her comrades but not the attackers. And yes there is more than one.
