Since we have so little information, it's possible that 'the great blank' was a creative or experimental title for a novel in 1925. It could have been a work that explored new themes or literary forms for that era, but without further research, we can't be certain.
To add a blank page in a story, you could try this. First, find the insert option in your software. Then, look for the option to insert a new page. It should give you the blank page you need. Sometimes, depending on the program, you might need to adjust the page settings to make sure it's truly blank and fits your requirements.
One way to do it is to simply not mention the name at all and describe the character through their actions and characteristics instead. This can create a sense of mystery. Another option is to use something like 'The Mysterious Stranger' or 'The Nameless One' to imply the absence of a specific name.
Another option could be 'dark forest'. The adjective 'dark' creates an atmosphere of mystery and danger. In a game story, the dark forest might be filled with all kinds of strange creatures and obstacles that the player needs to overcome.
I don't think it is. Usually, such unique and strange concepts like Blank Room Soup are made up for creative purposes rather than being based on real events.
One possible answer could be to have a story about a mother's love. For example, 'On Mother's Day, I (bought) a beautiful bouquet of flowers for my mother. She was so (happy) when she saw it. Then we (went) for a walk in the park and talked about (memories) we shared.'
A simple idea could be a story like 'On Mother's Day, my family and I (planned) a surprise party for my mother. We (invited) all her friends. She was (astonished) when she walked in. We had (cake) and (punch) at the party.'
One possibility is 'fierce dragon'. 'Fierce' shows that the dragon is not to be trifled with. In a fantasy game story, the dragon could be a powerful boss that the player has to defeat to progress in the game.
