I'm tempted to give everyone access to a blue box. Then this insane argument about what's "valid RP" vs. "non-GM sanctioned" RP can go the rubbish bin.
And, if I hear one more OOC argument about "well, if it's not a blue box, I figured they're just insane," I think I'll turn you into a newt to enhance your roleplay.
If this response makes me a newt, so be it, but I feel that "Your premise is what's wrong."
Its not about "valid" vs. "invalid", its about opt-out vs. opt-in. If you actaully turn me into a newt such that I cant use my healing skills, I can still "opt-out" by pretending it didn't happen and trying to run around healing as usual (or hide in the library), but I'd just be living in denial as I still wouldn't be able to heal anyone. When someone like Zues claims he is an all powerful god and has just turned me into a newt, I could "opt-in" and run around acting newtish and not heal, but if I accidently equip my moonstone, they'd be healed. It really does boggle my mind that you don't want to acknowledge a difference between the two. Both can be fun, both can be good for the game, but there is most certainly a difference.
Lots of people roleplay in all sorts of ways, large and small everyday. Sometimes its very innocuous and costs me nothing to play along, sometimes its gamebreaking and completely violates everything I've previously experienced about the way the Clan Lord world works. Everyone has to draw their own line somewhere about what to go along with. For all those that are "too far out" for me, roleplaying that said person is insane and delusional is the only option I have for not breaking my own roleplay. If I pretend they don't exist and/or didn't say what they just did, then I'm the one breaking character. Saying I think they are insane is my version of "opt-out", and I find it deeply disturbing if you really don't think I should have that option.
As Althea hinted before, Tessa did a lot of roleplay that was hard to fit into the Clan Lord world as most of us perceived it. She claimed to have knowledge from a mysterious mind from another dimension that was the "real her". She believed she was both a fighter and a healer, something that we are clearly told by Hekus/Fistus is not an option. She asked us to believe that what were clearly perceivable as two different people (Tessa/Dr. Malthus) were in fact the same individual. All of this ultimately forced me to classify her as "insane", her actions and claims seemed to fit that description rather well. On the whole, that didn't prevent run of the mill hunts and what not, but when she starting claiming she was investigating an illness, it seems perfectly reasonable to continue to have our characters assume this was just another element of her insanity. After all, her ability to do so at all was based on "knowledge from another dimension".
Then she got a blue box. Seeing dews pop out of someones head was rather convincing that what she had been saying was, in fact, not entirely insane. Sure, I could "opt-out" and pretend I didn't see dews come out, but then I'd be acting insane in everyone else's eyes. In character, this kind of forces you to question yourself quite a bit. If she was right about this, what about all the other stuff? Maybe I'm the insane one thinking I see two different people, thinking that I couldn't be a member of both the fighter and healer guild when all the time I could have. Out of character of course, I knew that it was just that this time the GMs had given her the ability to generate a blue box. But in character I couldn't see how to rationalize that what I knew of the world made sense. As you may have noticed if you read Babajagas journal at the time, I stopped playing Clan Lord for several months. When I came back, I pretty much gave up on roleplaying my character in any real way as it just involved too much emotional risk.
This thread has at least given me some better understanding of why the GMs decided to give the Separ to her as she was embracing the plot line you were making available. Sadly, it was the fact that it was she, whom embraced it that made me, and probably others, largely ignore the plot line for so long. At the time it was rather shoking that the GMs validated "knowledge from another dimension" as a viable method for solving a great mystery in the lands. Perhaps in fact, the GMs simply didn't know about that part of her claims, I don't know. Still, it caused a great deal of confusion and I hope this post helps you see why some of the negative feelings existed at the time.
