I've recently discovered this secret area while playing through Pumpkin Pastures in Minecraft Dungeons.

Minecraft Dungeons pays a lot of attention to level design and detail, and it is no surprise that they've included this unsettling secret. In this short video, I reveal a hidden room hiding behind a pile of crates. Pull the sign with the danger sign, and a hidden entrance is revealed. Upon entering, you hear the laugh of a necromancer, and a couple vindicators are summoned. It seems to be one of those secret crypts, but this one does not reward the player after surviving the ambush. This might be some sort of lore hint.

I will be uploading more exciting videos about an SMP I've started last month, and I will be using my voice. I hope you enjoy my videos, and you should probably hit the subscribe button.
