I have a similar question as the one asked in 'How to write montages in prose? (fantasy novel)' however, there has been no answer in this and it is far too general.
The question I wish to ask is; Are there any specific techniques that you can use to write a montage, or a short sequence of events that take place over a period of time, in a novel?
For example, how would you write a piece of fiction that skims over a period of time but has scattered pieces of important information that is necessary for the future of the plot, may it be in the form of a work montage, training montage, or just an acceleration in time that would be too tedious to explain in detail due to repetition, but still have significant events that occur that are out of place?
Edit: To elaborate more on my specific issue; one of my characters is residing in a village to raise funds - and during this period, he sees injustices performed on villagers such as unfair extortion of taxes, bullying by more powerful beings, etc. How would I be able to string these in, as I don't want to include tedious events such as him going around helping out with farming, learning how to hunt, etc.? I've been considering including short chapters only a few paragraphs long in a sort of diary format, however I don't feel as if this would fit the third person style of writing I'm going for.
