Chrono Wiki:Featured Article/Fiendlord's Keep
The Fiendlord's Keep (also known as Magus' Castle in the SNES/PS version) is a location in Chrono Trigger that appears in 600 AD. It is Magus' castle and, according to legend, is home to 100 monsters.
Being the heart of the fiend world, the castle is permeated with magic. At first, there are two wings accessible. They can be completed in either order. The West Wing is populated with monsters who use mostly physical attacks, leading up to the battle with Slash. The East Wing is populated with monsters who use a great deal of magic, ending in the encounter with Flea.
After both wings have been completed, returning to the main hall will reveal a secret entrance to a third, central wing, hidden behind an illusion. This third wing is filled with traps of Ozzie's devising. After passing all of his traps, you will come face to face with the general. Defeating him is trivial, as you can use his traps against him and drop him into the basement through a trap door. This opens the way to a stair that descends into the catacombs beneath the keep, leading to Magus' sanctum. (more...)
