Guild Wars 2

So after beating path 3 instead of leaving I decided to explorer the stairs in that pit. Turns out there is a whole room hidden behind moss that’s not really a Jp but more of a walking puzzle that’s empty but if you fall you fall in water. I tried this the next time I went before beating the boss and it was still empty. Now my question is does anyone know if a certain path triggers something in here or was it removed or is there nothing to it?

Nope, its just exists for no reason.

Easter egg or something, or unfinished content.

It’s unfinished content. The designer of the JP said so in another thread (too lazy to find it).
