Scroll of resurrection

As Havar has stated, your friend will be provided a free month's worth of game time if you reactivate your account and purchase a month's worth of gametime, regardless of how much time has passed. I wouldn't let this deter you from playing the game if that's truly something you want to do, Zeka. Fights happen, but there's no reason to punish yourself just so that you can punish your friend as well.

I truly wish you the best and hope that you and your friend are able to make amends.
