Ive lost access to my account with my 60 druid. I will be returning to elysium in a few weeks and would like to take up where I left off. I cant remember what email I used, or what password, username etc. Im living abroad and I cant access my gmail or old hotmail account because of some stupid location security bullshit. How can I prove the character is mine? I can give names of some emails the account might be linked too, I can also give in dept details of what my character used to do.

I think i know the username, and i have 3 potential emails the account is linked to. Im blocked from these emails though.
