A block similar looking to the waytone.
When right clicked, it opens the warp screen like the waystone, but it will not added as a destination travel target.
It simply acts a different method of accessing the warp screen, allowing for a different kind of balancing for server owners/modpack creators.

It probably wouldn't even need any of the owner/protection logic the waystoned have and wouldn't even have to be a tile entity, making the implementation even simpler.
