Questions About Immortal Iron Fist

I don't have answers for all of these, but maybe you do. They're just questions I found myself with today. I guess I could wait until my next shipment brings this month's issue, but patience is not really one of my virtues.

1) Davos said that the 8th city was created to house monsters and demons that plagued K'un-Lun thousands of years ago. But they wouldn't have only been threats to that city, right? It took all the original Immortal Weapons to banish the creatures, so there had to be something in it for the other cities as well, since they don't seem to have been that chummy with each other prior to Danny coming along.

2) The reason Danny's going there is because there are many people the previous ruler of K'un-Lun dumped there for questionable reasons. How was that Yu-Ti able to send them in? yes, the gate is supposedly always open, but it doesn't appear to be something you can simply walk through. The Immortal Weapons had to use some sort of weird chi-focusing exercise to get through, and I can't imagine it's easy to get people to focus their chi and open the path to a hellhole you're about to throw them into, so how did that work? Did Yu-Ti have some special key that makes it easier?

3) This one is a bit older. In the Tournament of the Heavens, Davos represented the city of K'un-Zi, ruled by the Crane Mother. I'm wondering why she wouldn't have had any other suitable candidates come along prior to that? Yeah, Orson killed her weapon at the Tournament That Wasn't, but that was 70 years ago in the real world, no telling how long it was in K'un-Zi, since time seems to work differently there. The other cities can find new representatives in that timespan, witness the fact that the current Bride of Spiders is not the same one that came after Orson in the mountains of Tibet with the Lightning Lords of Nepal. It strikes me as odd the Crane Mother couldn't do better in all that time than an Iron Fist wannabe like Davos.

4) How Xao know about the 8th City? He's related to those Lightning Lords somehow, did they or some of their family spend time in the 8th City? If so, how would Xao have escaped (if he grew up their), or know about it, if he was born/grew up elsewhere? At this point, mentioning the 8th City seems to have been Xao dangling the carrot in front of Danny's nose, to lead him into a trap, which makes me think Xao is familiar with life there, but that still raises the question of how he left.
