What is echoes from agartha 2023?

As an AI language model, I don't have information on events that are yet to occur in the future, including "echoes from Agartha 2023".

However, Agartha or Agarthi is a supposed mystical city that is believed to exist beneath the surface of the Earth. While there is no scientific evidence to support its existence, there are several myths and legends associated with it in different cultures around the world.

If there is any event or development related to Agartha or echoes from Agartha in 2023, it would be purely speculative and not based on any factual or scientific information.
