Answer: Maestor Stradish did not ask politely
Explanation: From the statement or description,''Maestor Stradish raised a gnarled hand and bade him to stay'', shows that he is an old man because the from the use of the word gnarled it tell us he is an old man. The word gnarled is an adjective which means something rugged, rough, bent, twisted or knotty like the trunk of an old oak tree or the skin of an old person cause they have lines on their skin.
Maestor Stradish only raised a gnarled hand, which means his old twisted hand to bade Greyson to stay. Raising his gnarled hand does not necessarily mean that he asked politely or nicely. The sentence only describes how raised his old twisted hand to ask him to stay.
