"The sands are shifting..." What does that mean?

[SwordWolf]

So I played Fargo Souls today and when I entered a exposed pyramid, the screen started shaking and the status message "The sands are shifting..." appeared. I'm very easy to scare, so I left in fear. What would've happened if I didn't? as it didn't appear when i reentered the game.

The mod adds a new pre-hardmode boss fought in the Pyramid, around Eye of Cthulhu to Eater of Worlds tier, I assume it's related to that.

Just now I was playing the game and noticed the message. Ive seen it multiple times before and like you I didn't have an understanding of what this means. I dont know if I just got lucky or what, but when you see the message the sand near you shakes. So I decided to investigate and upon digging straigh down I came across a pyramid. So I assume the message just lets you know that there is a pyramid near you. You probably just got within triggering range of the message and tripped it while entering the pyramid.

for anyone wondering this has been reworded in the mod to "The sand is shifting underneath you..."!!
