Dark forest being a trope in other books is irrelevant to it being a huge spoiler for the series if you read the wikipedia which definitely will make the experience of reading it less enjoyable.

That's like saying murder is in a lot of books so it's not a big deal to spoil a book with a pivotal murder in its plot. Have you read the books? Because I would think the importance would be obvious if you had.
