This is a cave on Isla Inferno, guarded by Gorog. When Jolly Roger cursed the island the cave became with the curse that if anybody went in there they would see they're dreams would be seen through their eyes. But in reality they were being lured to Fear, and then he would devour their souls and give the dead corspe to the Hellhounds and they would be eaten. If a person escapes The Woods... the Cave of Insanity would be the first thing they were to see. Then they would see the Demon Boss, Gorog in his hugeness guarding the way in. But when pirates do make it there Gorog would sometimes allow them in because Fear would want more souls to feast on. It is a very good place to find famed weapons. But beware you might lose your mind trying to escape.
