— We'll all go to Hell (Hades or Sheol) when we die. King James translates the greek word "hades as hell...the hebrew word is "sheol" .
— Hell or Hades is where human spirits are collected by God or Where we all go waiting for the day of judgment.
— It is a spiritual realm. Some say it is below us other say it is above us. I think it can be anywhere.
— It is divided into two sections:
Section 1. Section for the good. Here the good ones are kept. It's a a place of peace, happiness and beauty. All the good are people (from every Nation that has ever existed) are restricted there until they meet God.
Section 2. The wicked ones are restricted in this section. It's is a section of torment until judgment and they are thereafter destroyed forever (the second death)
— The Son of God (the Judge of all Mankind) will appear in the sky in power and glory. He will destroy all kingdoms and their rulers.
He will raise the Saints and Martyrs
— After the destruction a hidden City, beautiful and everlasting will appear on Earth
— The Son of God will rule over every Nation for a thousand year with hundreds of thousands of people who believe in him. Those who will rule with him are Saints and Martyrs. The Holybook doesn't mention who or what they will rule over. I think they might be the rightous/good people from every Nation who don't know the Son of God. They will be risen from the dead and ruled by Son of God, saints and martyrs. This probably is to prepare them for the kingdom of God.
*Those are just my understanding*
— The son of God will finally judge the good and the wicked after His 1000yrs rule
— In the end we will be with our Creator in heaven. Sun does not shine in heaven according to Holybook. Our only source of light is the God. He brightness, righteousness and glory will cover the entire Heaven and its inhabitants forever and ever. It's like a mighty shield and will be a source of universal Holiness.

Isaiah 11:6-9
"A wolf will reside with a lamb, and a leopard will lie down with a young goat; an ox and a young lion will graze together, as a small child leads them along. A cow and a bear will graze together, their young will lie down together. A lion, like an ox, will eat straw. A baby will play over the hole of a snake; over the nest of a serpent an infant will put his hand. They will no longer injure or destroy on my entire royal mountain. For there will be universal submission to the Lord’s sovereignty, just as the waters completely cover the sea."
