Nightmare is an entity, a force of existence in Lucid Adventure serves the will of Zero which is the destruction of Lucid Adventure.


The exact origins of Nightmare are still shrouded in mystery but it seems to originate from Zero.[1][2]

The power of Nightmare seems to come directly from Zero, who infected her own core with a curse. This is the reason that although Nightmare grants temporary power, it ends up destroying everyone and everything as it is Zeros will.[2]

A year ago, A red player guild, Guild_Nightmare worshipped the existence of Nightmare which made them stronger with the more destruction they caused. This led to huge war that enveloped the whole of Lucid Adventure. They wanted to destroy the game in accordance to the will of Nightmare itself and caused a massive amount of destruction, the effects of which are still being felt to this present day.[3][4]

According to Yopi, the core of Nightmare was sealed.[5]

Players are banned by Giga from using the power of Nightmare as it causes disruption.[6]

Nightmare Usage in Lucid Adventure

Although players are banned from using Nightmare, members of The Giga Empire are not prohibited from using its power. The core of Nightmare which seems to be in Zero's head is currently with the Giga Empire. Sam Han had it fully analysed and Giga have essentially become Nightmare themselves.[8] Unbeknown to them, they are secretly being used by Zero to bring and end to Lucid Adventure.

Any player caught using Nightmare is arrested by the security and eventually banned from the game. Radish Kimchi was immediately apprehended after his Nightmare usage[9] and Hardcore Leveling Warrior would have been arrested were it not for the timely intervention of the God of Combat.[6]


Nightmare can be used in many ways, it can be used to boost the players stats and skills, it can be used to create 'bug' weapons that are capable of deleting players from the game, it also can be used to create some sort of armor.
