ATTN: ALL - MOD POST
Canon Puncturing - for lack of a better term, this is what we're going to call it. We're referring to the practice of sending your character up to another and saying, in essence, 'OMG u r not reel, u r a fictional character!' There's been a lot of this going on recently, on all sides, and we have this to say: STOP.

Don't ret-con any previous plotlines - what's done is done - but please, no more. It has the potential to create some very sticky meta situations which will only end up messing with everybody's heads.

If you want to create some existential angst for your own character by, say, having them find a copy of their canon lying around the bar, that's fine. BUT, before you do so, you will need to check for permission with every other character from that canon in the bar.

Likewise, if you should decide that another character is fictional in your world (and please, please, don't), before mentioning it in any way, shape, or form in the bar, you will need to receive consent from:

a) Every character from the canon you decide is fictional, and

b) Every character from your own canon.

For example, if Snow White-mun wanted to bring a volume of 'Revolutionary Girl Utena' into the bar, before they did so, they'd have to check with Bigby-mun (from their own canon), Anthy-mun, A-ko-mun, B-ko-mun, Akio-mun, and Utena-mun (from Utena-canon), even if the only person they intended to show it to was, say, Anthy.

In conclusion: every character in Milliway's is created equal. Everybody is real, so, unless you receive specific permission to do otherwise, please treat them as such.
