We were playing using the Kingsport expansion last weekend and got this rumor as our 3rd Mythos card.

It goes off when there are 3 clue tokens on it and it starts with one.
So ... 2 more clue tokens and all three rifts open.

There was no way we couls get a Blessing in time.

I have two questions here:

1) "Each time monsters with the moon dimensional symbol move, place a clue token on this card."
Does this mean when a monster token actually moves (there may be no moon symbol monster on the board) or when the dimensional symbol appears on the Mythos card? (We chose when a monster actually moves, otherwise it would open way too quickly)

2) It seems that FFG should have included tokens to put on the rift locations on the Kingsport board. When all 3 rifts open you don't know which group to close. Yeah, I know ... all of them, but when you close one group do you select which rift to close? (we decidef to choose which rift to close, but it never got that far to actually close and we wound up in an Epic Battle)

We randomly chose Hastur, then selected Hypnos as the guardian and a random Herald.
The Herald turned out to be Tulzscha, what an excellent pair, Hastur and Tulzscha.
Besides flying cultists, they were now elusive and gobble up Elder Signs.

We barely made it out alive.

1) I'd say every time the Crescent moon dimensional symbol appears as monster movement on the Mythos card you have to place a clue token on the card. It doesn't matter if there are moon monsters on the board or not

2) Don't really know. Never happened to me to have more than one rift open at a single time. In the case you highlighted, I'd probably try to remember which rift belonged to which track, in order to close them in the proper order

I'd assume you can choose to close any open rift since A) there's no tracking device B) there's no explanation of how to play it in the rules and C) it's insignificant unless you have arcane insight.

1) I think the card could have been worded better to clarify its intent. At first I felt the same, crescent moon symbol on mythos card causes a clue token to be added to the Rumor. After reading it again, it can be interpretted to mean when monsters with moon symbol move place a clue token on the card.

Maybe I'm reading to much into it.

Q: World Torn Asunder – Does a monster with the moon dimensional symbol on the board have to actually move or does the effect simply trigger if the correct monster movement symbol appears on the Mythos Card even if there are no monsters on the board?
A: No monster is needed to trigger the effect.

This means that the Mythos symbol determines the clue placement.

Also, just for fun:

Q: World Torn Asunder – If you fail this rumor, do all three Rifts appear at the same gate location as the card which placed the final token on the rumor?
A: No, 3 different places. Draw 3 Mythos Cards to determine where they appear.

And yeah, I'd say that you just simply choose which rift you're closing. Not that it would make a world of difference though.
