Young Thomas has come to the castle to be a page. He's being given a basic education - nothing too fancy - as well as being taught manners and how to be a knight. He serves Lord and Lady Sherwood food at the High Table, which is a great honour.

When Thomas is older, he'll be a squire like Baldwin who looks after a knight. Baldwin helps Sir Geoffrey dress and takes care of everything from his master's weapons to his horse. Both Thomas and Baldwin hope to be a knight one day too.

If a squire is lucky, and has proved his worth, Lord Sherwood will 'dub him' a knight - with a tap of a sword on each shoulder - at a special ceremony in the name of the king. Then he can call himself 'Sir'.
