The Esper beyond the door has a time limit, and if you're at high levels, you can easily beat him. He does tend to spam "Prime Lvl Death" when he's got low HP (which sucked because EVERYONE was level 43 when I fought him) but aside from that, he's a total cakewalk compared to a lot of other Espers.


Beyond him, there's a secret path that leads into the Garamsythe Waterway, but that's a very small detail in of itself. The Deathbringer is a nice sword, but at +90 to attack, it's probably below or equal to your current weapons. It occasionally (or in my case, consistently) inflicts KO on your enemies, which actually annoyed me when I was attempting to steal loot.
