With his network of spies, the Spider knows all, but tells very little. Many times, it’s difficult to determine whether Varys is good or actually the embodiment of evil. Everything he does is part of the Spider's web.
As Master of Whisperers he is feared by nobles and common people alike. He has thousands of spies all over Westeros and Essos and has them so tightly in his grip that he can trap anyone in his web whenever he wishes. Varys is called the Spider because he spins his web everywhere.
