Demoriel is the great & mighty Emperor of the North, who hath 400 Great Dukes & 600 lesser Dukes with 700,000,800,000,000,000 servants under his command to Attend him, whereof we shall make no mention but of 12 of the Chief Dukes & their seals which is sufficient for practise.
Note each of these Dukes hath 1140 servants who Attend them as need requireth, for when the Duke is called for, & you have more to do than ordinary, he hath more servants to Attend him.
