Even during the first visit it's no fun. It's overun with zombies and spiders and spirits and the boss is the Lovecraftian Piscodemon. Before you cleared it, another adventuring party didn't have such good luck. This healer got her tank killed and is carrying around his head. Fast forward to the post game and one of the other members of that party has gone missing and the last one asked you to find her. So you go back into Tam Tara. The first boss is the missing member. She's dead and controlling a hoard of zombies. The second boss of the dungeon is simply called Spare Body. It's creepy. Then you get to final boss. That healer has gone off the deep end and that head she's carrying morphed into this flying abomination that you have to kill and the whole time, she's laughing.
And then after the boss, she falls off a cliff. Smiling as she falls. Then while you're talking to the one remaining party member this image flashes like something from a survival horror game. (SPOILER)
Here's the BGM for the dungeon.
It's been like three years and it's still my favorite dungeon.
