Quick question on the Heroes travelling the overland map, can the party move through the overlord's keep location or must they go around it?

I know that they cannot move to that location, my question is using the Staff of the Wild can they move from one side of that location to the other without stopping there?

Thanks

My assumption at this point is that no, they cannot.

Regardless of the game effect of the Staff(ie, placing the party token two spaces away rather than one), the party token cannot enter the OL's Keep space. As the trail is linear and the staff of the wild allows the heroes to travel along two trails it means that the party would have to travel to the OL keep space and then beyond. Since they are not allowed to travel to that space the Staff is not a free pass through it either.

Correct. Note though that this is one of the changes between RtL and SoB. In RtL, the heroes are forbidden from entering the Overlord's Keep's Space. In SoB, they can enter the space just they cannot explore that dungeon.
