I was wondering, how do you interpret Darkvision here....the rule books never give a definite description of it, and so most people just say that they are able to collect what little light there is to see...but as I understand it, most of the Underdark has absolutely no light, but in R.A. Salvatore's books they seem to take it as being able to see heat, which opens up more possibilities, such as the drow sign language described in R.A. Salvatore's books. I just wanted to know what you guys use so I don't screw up at a later time.
