Guardian Pylons is a mod that replaces all the existing obelisks on the map with pylons. It was created by the creator of the mod, and it's the only thing that was changed. It doesn't change the texture of the blocks, nor the world generation. The only thing that is changed is the appearance of the blocks.

The pylons look like obelisks, but they are much longer and have a different texture. They are also much heavier, and they have a different sound effect when you jump on them. They are placed on the map in the exact same way as the original blocks.
