As we know, Lord Varys from Game of Thrones was one of the true well-wishers of the seven kingdoms and a brilliant diplomatic person of Kings' Landing. As per my knowledge he had no relationship with any royal family.
What he actually did for the kingdom made him a member of the council who took important decisions for the kingdom.
But one question, I had seen that he had put some person in the box as a prisoner. Who was he? Was Varys torturing him?
