Atman

From LSWiki

   Atmai

   Your atman (plural: atmai) is your master account that your incarnoi
(singular: incarnos) are attached to.  You can have up to twenty-five incarnoi
on your atman.  When you 'disincarnate' (or 'quit') out of Lost Souls, you are
taken to the atman menu, which has its own set of options for you to use.

   Some settings, like your terminal type and email address, are atman-wide
and do not need to be set for individual incarnoi, while other settings, like
combat behaviors, are specific to one incarnos.
