What is the purpose of the hidden rooms next to the arena in Svargrond?

Question

While browsing the map in cyclopedia we can sometimes come across some interesting facts. It turns out that there are some small hidden rooms next to the Arena in Svargrond.

It seems that these locations are not available to players. Naturally, a question comes to my mind. What is the purpose of these rooms?

Comments

I have no idea of their use but they remind me of the room using for trigging raids in Zao. https://www.tibiaqa.com/16182/how-does-the-mysterious-raid-triggering-room-works?show=16182#q16182

Answer 1

There are switches on those rooms which are part of Svargrond arena's mechanism such as character entering a room + creature (of the correct difficulty level) spawning, character leaving arena, and character being kicked out due time limit.

Answer 2

This was one of Cipsoft's old plans, which got forgotten over time, just like the famous addon 3. The plan of Cipsoft was to add a fourth Arena in Svargrond.

Do you have any source for this information? When you write about the fourth, do you mean the fourth difficulty level of the arena?

@Kczae, the OP did not mean the room next to the 3 reward rooms.
