Hi Guys.
The text on the card reads
When this card enters play, place the Mystery token on space 6.
As an encounter, an investigator on space 6,may explore the underground city of K'n-yan by resolving a K'n-yan Unearthed Special Encounter
At the end of the Mythos Phase, if there are Eldritch tokens on this card equal to half "investigators", solve this Mystery.
Do you leave the Mystery Token on space 6 after an encounter, until you have solved the K'n-yan Unearthed Mystery? If not, how do I get more than one Eldritch Token on the card?
Cheers.
