I'm not sure specifically who 'Terry Bolryder' is within 'Fantastic Fiction' without more context. It could be an author, a character, or someone related to the Fantastic Fiction community in some way.
Terry Fox was a remarkable individual. He was a cancer survivor who, instead of giving in to his illness, chose to fight back in an extraordinary way. He became a symbol of courage as he set out on his Marathon of Hope, aiming to make a difference in the fight against cancer.
I don't have enough information to determine who Terry is exactly. He could be a real estate agent, an investor, or just someone with interesting real estate experiences to share.
It's fictional. Terry Jones might have used The Crusades as a backdrop to tell a story that involves fictional characters and plotlines, rather than presenting a strictly historical account.
I think 'Going Postal' can also be good for beginners. It has a clear and engaging plot about a con - man who has to turn around the Ankh - Morpork post office. It's full of Pratchett's clever wordplay and unique characters, and it gives a great sense of the Discworld setting.
