How do I move a hero onto a cell?

Guys! Help! My hero went through the gate of the border guard (I visited the keymaster's tent), then went through the portal. There are gates of the border guard again. And I can't go through them. I'm standing on the portal and can't go either left or right. Basically, I need to go through the portal I'm standing on. How do I go to the same cell I'm standing on? Is there such a function?
