It said in the guide "Characters with XP Level 1 are wiped after 9 months of inactivity, all characters above Level 1 are retrievable at any time. Dead characters, however, can never be retrieved."
What if your character has no XP whatsoever?
You're allowed as much inactivity as you want. It means if you're a level 1 character, after 9 months of you being inactive your character will have been deleted and you would have to create another one.
I think that members of Krath Dynasty perform ritual sacrifices. I believe that this is a fancy term for executions, so you might want to ask them to execute you as a ritual as it might be the fastest way to get your character killed.
