In the context you use it the implication is you're aggregating lore from multiple sources, which you're not.
Look man, I'm not trying to come down on your content, I'm just saying it's best practice to be upfront about where you get your information. If you're going to quote a blog word for word, just tell your audience that. People can't read, and you went through the trouble of adding graphics and video. That's not nothing, people appreciate that. You wouldn't turn people off by citing your sources.
