Immortality Revisited v2.0
Do you want to live forever?
You may, if adult, decide to become a normal immortal (immune to aging or death from old age), an enhanced immortal (adds immunity to diseases and battlefield deaths), or a hero immortal (adds a huge stat and leadership boost.) You may also, while immortal, choose to become mortal once again, or grant your spouse, adult children or rivals immortality, or remove immortality from them. Any of these you grant immortality to are normal immortals.
This changes many event files, so may be incompatible with other mods.
