Warden dimension

Hl Mojang, i just wanted to propose an idea for a new minecraft update. Minecraft is a great game and you keep adding amazing and new stuff to make it a beautifoul game. But I want to give u a suggestion, what if the Warden had it's own dimension? I always wondered what is that big portal in the Ancient city, and i tought that a new dimension would be a great addition to Minecraft. Picture this: A sistem of caves made of Sculk and living material, the home of the Warden and vary hostile mobs, new biomes with new blocks and new structures, there could also be new weapons or tools, but it would be very nice to se this addition in game P.s: I hope that someone see's this, i'm a 13 year old boy that lives in Italy and i cannot wait for more minecraft update's, but if you decid to make this one, it would really make my day. Thank's Mojang for listening. Bie.
