They are a return to Nihl.
No, sinners will be in hell, which is a conscious place of suffering for eternity. All people will be resurrected: good and bad, and judged together. This is Orthodox teaching. Here are the texts from the Sunday of the Last Judgment that prove this.
RIGHTEOUS JUDGE OF ALL MANKIND!
YOU WILL COME TO JUDGE THE LIVING AND THE DEAD,
ENTHRONED IN GLORY AND ESCORTED BY YOUR ANGELS.
EVERY MAN WILL STAND IN FEAR BEFORE YOU,
TREMBLING AT THE RIVER OF FIRE FLOWING PAST YOUR THRONE,AS EACH ONE WAITS TO HEAR THE SENTENCE HE DESERVES.
ON THAT AWESOME DAY HAVE MERCY ON US AS WELL, O CHRIST;
COUNT US WORTHY OF SALVATION,
FOR, WORTHLESS AS WE ARE, WE TURN TO YOU IN FAITH,//
COMPASSIONATE AND MERCIFUL LORD!
THE BOOKS WILL BE OPENED AND THE WORKS OF ALL MEN LAID BARE:THE VALE OF TEARS WILL ECHO WITH GNASHING OF TEETH;
THE SINNERS WILL MOURN IN VAIN, AS THEY DEPART TO ETERNAL DAMNATION.
YOUR JUDGMENTS ARE JUST, O LORD ALMIGHTY!
WE BEG YOU, MASTER, FULL OF GOODNESS AND COMPASSION://
TAKE PITY ON US WHO SING TO YOU, MOST MERCIFUL ONE!
THE TRUMPET SHALL SOUND AND THE GRAVES BE OPENED:
ALL MANKIND WILL ARISE IN TREMBLING;
THE RIGHTEOUS WILL REJOICE, AS THEY RECEIVE THEIR REWARD,BUT THE WICKED WILL DEPART TO ETERNAL FIRE WITH WAILING AND HORROR.
LORD OF GLORY, HAVE MERCY ON US!
NUMBER US WITH THOSE WHO LOVE YOU, MASTER,//
FOR YOU ALONE ARE GOOD!
I SHUDDER IN TERROR WHEN I THINK OF THAT DREADFUL DAY;
I WEEP AS I CONSIDER THE DARKNESS THAT WILL NEVER SEE LIGHT:
THERE THE WORM SHALL NOT CEASE, OR THE FIRE BE QUENCHED;THE PAIN OF THOSE WHO REJECT YOU WILL NEVER END.
SAVE ME, YOUR MOST WORTHLESS SERVANT, RIGHTEOUS JUDGE,//
FOR YOUR MERCY AND COMPASSION ARE MY ONLY HOPE!
WHEN THE THRONES ARE SET IN PLACE AND THE BOOKS ARE OPENED,
THEN GOD WILL TAKE HIS PLACE ON THE JUDGMENT-SEAT.
WHAT A FEARFUL SIGHT,
AS THE ANGELS STAND IN AWE AND THE RIVER OF FIRE FLOWS BY:
WHAT SHALL WE DO, WHO ARE ALREADY CONDEMNED BY OUR MANY SINS,AS WE HEAR CHRIST CALL THE RIGHTEOUS TO HIS FATHER'S KINGDOM,
AND SEND THE WICKED TO ETERNAL DAMNATION?
WHO AMONG US CAN BEAR THAT TERRIBLE VERDICT?
HASTEN TO US, LOVER OF MANKIND AND KING OF THE UNIVERSE://
GRANT US THE GRACE OF REPENTANCE BEFORE THE END AND HAVE MERCY ON US!
WHEN YOU, O GOD, SHALL COME TO EARTH WITH GLORY,
ALL THINGS SHALL TREMBLE,
AND THE RIVER OF FIRE SHALL FLOW BEFORE YOUR JUDGMENT SEAT,
THE BOOKS SHALL BE OPENED AND THE HIDDEN THINGS DISCLOSED;
THEN DELIVER ME FROM THE UNQUENCHABLE FIRE,//
AND MAKE ME WORTHY TO STAND AT YOUR RIGHT HAND, RIGHTEOUS JUDGE!
Terror and amazement seize me
when I think of the unquenchable fire of Gehenna,
of the bitter worm and gnashing teeth.
But release me and forgive me, O Christ,
and set me in the ranks of Your elect.
Unworthy though I be,
may I also hear Your voice
that so greatly desired, calls Your saints to joy,
and may I attain the ineffable blessings of the Kingdom of heaven. When at the judgement of the world
You will separate the sinners from the righteous,
count me as one of Your sheep
and do not place me with the goats, loving Lord,
but may I hear Your words of blessing.
The river of fire devours and torments me;
the gnashing of teeth grinds me to dust.
The darkness of the abyss fills my heart with dismay,
and what can I do to gain God's mercy?
Spare, Lord, spare Your servant; do not deliver me to the bitter tormentors,
to the cruel angels of hell,
who will never let me be at rest.
Lord, Pardon, remit and forgive all my sins against You;
do not condemn me there, in the presence of the angels,
to the punishment of fire and to unending shame.
Deliver me, Lord, from the gates of hell,
from chaos and darkness without light,
from the lowest depths of the earth and the unquenchable fire,and from all the other everlasting punishments.
Lord of supreme love, as I think upon Your fearful judgement seat and
the day of Judgement, I tremble and am filled with fear, accused by my
own conscience. When You sit on Your throne and bring all to trial
then no one will be able to deny his sins, for the truth will accuse
him and terror will hold him fast. The flames of Gehenna will roar
and the sinners will gnash their teeth. Therefore have mercy upon me
before the end,//AND SPARE ME, RIGHTEOUS JUDGE!
Terror seizes me when I think of the unquenchable fire,
of the bitter worm, the gnashing of teeth, and soul-destroying hell;
yet I do not turn to true compunction.
Lord, Lord, before the end, strengthen Your fear within me.
When You, O God, shall judge all things,
who among us earthborn, beset by passions,
shall dare to stand before You?Then the unquenchable fire and the destroying worm
shall seize the condemned and hold them fast forever. The Lord comes to punish sinners and to save the righteous.
Let us tremble and lament,
and call to mind that day when our hidden secrets will be disclosed
and He will pay us what is due.
BEHOLD, THE DAY OF THE LORD ALMIGHTY COMES,
AND WHO CAN ENDURE THE FEAR OF HIS PRESENCE?
IT IS A DAY OF WRATH; OF THE BURNING, FIERY FURNACE,
AND THE JUDGE SHALL SIT, GIVING EACH THE DUE REWARD OF HIS WORKS.
I THINK UPON THAT DAY AND HOUR
WHEN WE SHALL ALL STAND NAKED AS MEN CONDEMNED
BEFORE THE JUDGE WHO RESPECTS NO MAN'S PERSON.
THEN THE TRUMPET SHALL SOUND
AND THE EARTH'S FOUNDATIONS SHALL SHAKE: THE DEAD SHALL RISE FROM THEIR GRAVES,
AND MEN SHALL BE BROUGHT TOGETHER FROM ALL GENERATIONS.
THEN EACH MAN'S SECRETS WILL BE OPENLY BROUGHT BEFORE YOU,
AND THOSE WHO HAVE NEVER REPENTED SHALL WEEP AND LAMENT,
DEPARTING TO THE OUTER FIRE;
BUT WITH GLADNESS AND REJOICING//
THE COMPANY OF THE RIGHTEOUS SHALL ENTER THE HEAVENLY BRIDAL CHAMBER!
HOW SHALL IT BE IN THAT FEARFUL DAY AND HOUR,
WHEN THE JUDGE SHALL SIT ON HIS DREADFUL THRONE!
THE BOOKS SHALL BE OPENED, AND MEN'S ACTIONS EXAMINED,
AND THE SECRETS OF DARKNESS SHALL BE MADE PUBLIC.
ANGELS SHALL MOVE QUICKLY, GATHERING ALL THE NATIONS:
COME AND HEARKEN, KINGS AND PRINCES,
THOSE WHO WERE SLAVES AND FREE, SINNERS AND RIGHTEOUS, RICH AND POOR:
FOR THE JUDGE IS COME TO PASS SENTENCE ON ALL OF THE INHABITED EARTH!
AND WHO SHALL BEAR TO STAND BEFORE HIS FACE IN THE PRESENCE OF THE
CALLING US TO ACCOUNT FOR OUR ACTIONS AND THOUGHTS BY NIGHT OR BY DAY?
HOW SHALL IT BE THEN IN THAT HOUR?
BUT BEFORE THE END IS HERE, MAKE HASTE, MY SOUL,//
CRYING: TURN ME BACK AND SAVE ME, ONLY COMPASSIONATE GOD!
