Constructs trusted to protect the gates of the astral realms, made by gods, fueled by all of the humanity.
These constructs were created 2 billion years ago by the elder gods of the astral realms. Their sole purpose is to guard the gods at any cost. They attack the evil or chaotic aligned characters and allow lawful neutral, lawful good, true neutral, and neutral good to pass with good reason. These are hulking monsters above 50 ft tall and 30 ft wide. They have a rare metal known as Protonium coursing through the cracks in the surrounding stones. This metal is highly durable but rigid, this prevents extra attacks. These a pristine in form and cleaned and polished regularly allowing the star light to glint off of the rock itself. The stone parts are a deep silvery color where as the exposed metal is a metallic and shiny ivory color. They are usually encountered in pairs.
