Interestingly, all of us from Fodlan remember the Professor being shoved forcefully through a rift somewhat like the ones here - and them returning. Maybe the wide range of timelines pulled in from Fodlan is because the... you called it spacetime? is already weak in Fodlan. Like a frayed cloth. I wonder if the reason we're seeing the creatures we are is that those worlds have the weakest barriers around them?

I appreciate that. I just did not want to assume, as I have been informed this is a very dangerous situation and caution towards new people would not be unexpected.

I think your ideas are interesting and find the inability to easily share resources between nations frustrating.
