If your character died of old age and was cremated.
Then the Legendary Phoenix of Atranock can restore what it could from the ashes, to be able to rise again upon your summons.

If your character:
1) Existed at any time after 1 November 2015
2) Attained the rank of Captain or higher or was any of the Arch races
3) And your character was autodeleted
Then:
You can resurrect it from the ashes by:
1) If you still have the original moa file, just login using that file. Note you will need to resave the moa file immediately after exiting the game.
2) If you do not have the original moa file, you will need to speak to a god to get the archive file restored and a new moa file saved and sent to you.

Note that during the cremation:
1) All your items were burnt to ashes. All the Phoenix was able to save was the gold value of those items.
2) All of your stats were reduced to the minimum. The Phoenix was able to restore your invested points into points available to be used.
3) Gold was capped at 500K to avoid reintroducing gold that was exploited by historical bugs.

FYI there have been 1123 characters auto archived, a couple of hundred of which are still live in the game.
We will normally rename the lowest ranked version.
If there are duplicate names of characters, then you will need to ask a god or imp to rename one of them.
