Gem of True Sight

[donut3.5]

I know this has probably been asked a billion times plus more, but what the heck does the Gem of True Sight at the bottom right hand corner of the terrain do?
All I've figured out is some weird dwarf taunts you when you spam click it, and it also plays death animations when you delete it...
But is there any practical use for it?

Nope, thats it, you got it all

if you over spam it it can lock up your editor (trust me on that one) but other than that its mainly pointless... to my knowledge anyway.
