Crossroads

Crossroads allow teleportation to any crossroad that are linked to. You link a crossroad to another crossroad by taking a sign from the destination crossroad to the crossroad you would like to link to it. Crossroads are only buildable in a village claim and only by that village's Lawspeaker or Chieftain. Crossroad signs may only be taken from or attached to a crossroad by that village's Lawspeaker or Chieftain. Teleporting using crossroads causes travel weariness, which can be removed by sleeping in a bed, drinking alchoholic beverages, or smoking tobacco.

"Just for reference, you can travel both to and from a signpost so long as it is on a village claim, even with absolutely no authority at all. However as soon as the idol is destroyed, the sign becomes totally inactive, and the menu can't even be opened, nor can the sign be interacted with in any other way." ~ Quoting Zamte from H&H Forum
