Bottomless Bog (Final Fantasy III)

Shielding the Mansion of Goldor from outsiders without the Levigrass Shoes lies a bottomless bog that is found within Final Fantasy III. The bog can be described as a bundle of black lines.

The Bog's Purpose
Goldor lives nearby this bog because he fears anyone trying to steal his beloved possession, the Gold Crystal, which is also why he chained the Enterprise. If the Warriors of the Light try to go and take the Chain Key from Goldor without the aid of the Levigrass Shoes found in the sewers of Amur given by Delilah, the end result will be an instant Game Over. However, if the warriors have already met with Delilah and have the shoes, the Warriors are from that point on immune to the lethal effects of the bog, and can cross the deadly swamp to Goldor's Mansion.

Trivia

 * The swamp is similar to the Statues Of The Quest that cause an instant game over if the proper equipment is not found, that being the four elemental fangs.
