Reign could feel the anchor point being somewhere around the giant tree, but even after they had arrived in front of it they weren't able to see it. An anchor point is extremely easy to spot as it was a tear in space and wasn't inconspicuous at all. Them not being able to see it meant that either it was hidden beneath the ground or there was something else hiding it.
Reign and the others walked around the giant tree and looked everywhere around it but there was simply nothing there, it was just a gigantic tree that didn't even have any fruits growing from it. They thought that maybe the anchor point was hidden beneath the tree but Reign assured them that that was not the case as he could feel the anchor point and it was definitely in front of them.
