Could I get a character sketch of Duke Senior of As You Like It by Shakespeare?

The father of Rosalind and the rightful ruler of the
dukedom in which the play is set. Having been banished by his usurping brother,
Frederick, Duke Senior now lives in exile in the Forest of Ardenne with a number of
loyal men, including Lord Amiens and Jaques. We have the sense that Senior did not put
up much of a fight to keep his dukedom, for he seems to make the most of whatever life
gives him. Content in the forest, where he claims to learn as much from stones and
brooks as he would in a church or library, Duke Senior proves himself to be a kind and
fair-minded ruler.
