Solitary intelligent monsters often get into the same boat as the Kuo-Toans. Since the Roper really has no society (and possibly the most obscure language in Core D&D), it’s very difficult for it to understand the possible ramifications of offending pan-humanoid society. So now they’ve done it, and they really haven’t noticed the fallout they are receiving from that decision. Ropers pretty much attack anything they see, and now everyone that sees a roper attacks them. In the D&D worlds, ropers are on the brink of extinction and it probably never even occurs to them that their heavy tendrilled dealings with the other races have pushed them to this state.
