Writers do not devote the time to making About/Biography and/or Headcanons pages on their character blogs for their own benefit. They make these pages for the benefit of other RPers.
Such pages are especially important in the cases of Original Characters. Cause this means that generally a person has had to put a lot of time and research into developing pretty much a whole universe around this character. Even more so when they’re an OC for a particular fandom, cause this means they have to not only create this entirely new entity on their own, but they have to find a way to make them fit into a pre-existing universe and adhere to it’s rules and canon.
Now you may not think those things are important regarding a canon. They’re canon right? If you’re a fan you already know about them, right? Well sure, but no two people play the same character the exact same way. Cause they may perceive that character differently than you do, so their headcanons are different and it affects how they play their character. Not only that if their character is from kind book that’s been adapted into a movie, you don’t know which source they’re playing from. So don’t disregard stuff written by the mun just cause they’re playing a canon.
So regardless of whether its a canon or an OC, to completely ignore all those things they’ve written is pretty rude if you think about it. Cause as stated earlier, they weren’t doing it for themselves.
Yeah I know no one likes to really read, but it won’t hurt you to just take a minute or two to just sit down and read the things they’ve written and requested people have a look at before engaging their character in play.
So please, be a considerate RP partner and do your fellow RPer a solid and read their stuff. Canon or Original character.
