Unlike the Nightmare Light, the Obelisk's insanity aura is not dependent on it being active. At 800 sanity drained per minute, its effect is similar to that of a fully-open nightmare light, and players should avoid standing close to one, unless they have the means to restore the sanity and get past the Obelisk blockades.
The Nightmare Rampart is a naturally spawning object exclusive to Don't Starve Together, introduced in Return of Them. They naturally appear in front of the entrance of the Lunar Grotto biome after the Archive Switch within the Ancient Archives has been activated. They spawn Nightmare Fissures around them, which will in turn spawn Shadow Creatures. This will trigger a battle between Nightmare Creatures and Greater Gestalts in the Lunar Grotto. They never disappear even if the Archive Switch is turned off.
Nightmare Ramparts also have a massive sanity aura of -800 per minute.
Tips
Wearing a Bee Queen Crown can make sanity skyrocket in seconds by being near the Nightmare Rampart.
The area around Nightmare Ramparts is great for collecting Nightmare Fuel as it's easy to keep sanity low while fighting the Shadow Creatures that spawn from the nearby Nightmare Fissures. This can be further improved with access to Blue Caps from Mushroom Planters or the nearby Blue Mushtree Forest to keep sanity low and health high. Finally when done, the Bee Queen Crown can be used to quickly restore sanity.
