The area around the nature mana natural rune was still blocked off. However, it was in a much smaller way. This was just to ensure that there were not issues as time went on. There could always be someone that had the desire to experiment again. Let alone someone who wanted to sue the rune for their own needs.
Right this second, the best thing to do was make sure the area was safe while the arcane architect built the remainder of the tower around the odd crystal that formed when the rune fully came together.
The news of this successful formation was also restricted. Mosty to prevent the chances that someone else will try to force a rune like this again. While the natural runes clearly had their own rules and their own boons, they came with dangers. They could easily cause rune formations to collapse. Easily cause people to become greedy. Or even worse if not used properly.
