Submit a ticket to support explaining your situation, request they change the email to an address you have access to, and that they reset your password.
Support are rightly going to be cautious with such a request. When you submit the ticket you will need to include as much information about the account as you can recall. They need to make absolutely sure that you are the owner of the account.
Try to include anything you can remember about the account. What passwords you have used for it in the past, let them know roughly how many times you changed the password, any email addresses it was attached to (or tell them that was the only one used if there were none)
If you ever used a credit card to purchase drachma, include the credit card numbers you might have used (this is a huge help) or at least let them know how many purchases you made and what value you tend to buy,
What coalitions it belonged to - name some accounts that it has listed in its ally list, friends list, etc
Roughly what date you created the account if you can remember, the location you were when you created it
if you have a fixed ip address - what address you would have had when the account was created.
If you have access to the computer you used to play the account in the past - you can get the computer id number from it.
any thing you can recall about the account should be put in the message box - the more details you can remember the better the chance of recovery
If they write back from support asking for more information - try to return everything you can remember.
The process took about a week for people I know that returned to the game and recovered accounts they had abandon long ago.
Be patient with the support staff - they truly need to make absolutely sure you are the owner of the account as many play tricky games trying to hijack accounts.
I hope this helps.
My favorite games are shooters (Far Cry, Half Life, Bioshock and so on), and action-adventure games (The Witcher is my favorite one). And of course, I like war strategy games, like ours.
