Please, people, don't just tell me not to accept these terms. Tell me what to say, and what to counter-offer. I get that these are not the terms we should accept. But I don't know what we should accept/propose, and I know damn well that just saying "we shouldn't accept this" without giving an alternative will only lead to Bad StuffTM.
Make a border; we stay in China, we have proof that the plague IS BECAUSE OF THE CISHARNI and we can show it. I did flavor in fluff about some kind of magic-discs that act like hologram projectors depicting such--you can fluff bringing one of them to help depict proof.
That's the last resort offer--China is the borderline; we're here to stay. Issue terms of communication with the Cisharni too, with bearing from Sind, and probably issue vague warnings that catch their attention (i.e. we aren't the only major powers here, there is a danger to the west), which makes sense because 'hey uncharted lands :B', and can be regarded as idle musings.
Alongside that, it can be noted that we know they've been spying in China and planning a coup for the Dragon Emperor (at least, we got their spy anyway, you have Serrana [forgot spelling sorry]). We have proof of better living conditions all around. You even have proof of links between Orion and Artemis; call them out! (Oh and that thing with Turangol? That too; the GM has never mentioned mindlinks but that's all implied since forever -.-). I'm not sure what terms are most acceptable but we can make a roll on insight for terms delivered.
