Lion Lair Door Clue

I found something in the lion lair which is north-east of Bremminglar. I'm not sure if it was like this before the update, but here is it.

Go in the lion lair, then go East to the coordinates of 870, 24, -2320 (Y coordinates are important)
You should see a sign saying "You will find the key behind the first of three." with a door to the left of it.

Was this here before? Is this a clue?

 

It's as old as the lion den.

 

Old or not, You do not know.
It is worth looking around. to make sure we don't miss something
You guys need to stop saying its old or not, The server got updated and some stuff has changed but its hidden and we have no idea about it..

Might want to look around.

 

They're not assholes, do you really think they'd change already existing puzzles to make them related to ???
And I already checked there.

 

Problem is, I can't get in there. Can't do anything without "the key"

 

First of all, I did not say they're assholes, You do not know, they might have hidden something into that place without you guys know anything -.- Dafuq?

Plus they're Developers and they can change something simple in a blink of an eye...

 

Behined the first out of the three columns there is a button it opens the doir to a short parkour abd a tier 3/4 chest (maybe even a mini boss I don't remember)

 

Do you see that almost 5 x 5 fire on the left of the "boss room"? You could easily fit a 3 x 3 door in the middle. Why would they make that.

And now I realized I am useless lol
