Cavern of the Sea King [Solo]

It is said that the Cavern of the Sea King, once an altar of the Sea Kingdom, now consists only of ruined structures and a standing altar deep within. Protected by some mysterious power, this place remains untouched by seawater despite being located at the bottom of the Abyssal Depths. This is where the evil consciousness of Lord of the Abyss's is sealed, and it has been one of the Sea Kingdom's forbidden mysteries for centuries. However, with Madebi's betrayal and collaboration with Nightfall Witch, they have broken open its seal. Under the influence of Lord of the Abyss's evil consciousness, this place has become a dwelling for Evil Spirits. It is filled with miasma that drains life from living beings and Evil Spirits roaming everywhere. This also prevents Glory Shield from breaking through to stop further damage to its seal.
