Here's the thing I was thinking about for Lars:

The idea Lars had finally had just too much exposure to the various
types of `wierd shit' over the past few years... Vampires and secret
cabals are one thing, but then we have mages, clerics, and dragons.
Then we have the `demons', or whatever they are; the `big bibilical
evil'.  And then C--n, angels, and wrath-of-God stuff happening.  And
now, finally, we have the personal interview with God.

Basically, the idea is that Lars has found a `mission in life' again
-- a `Mission from God'.  While he may not be sure about the whole
`origins of man' thing, what he *does* know is good enough -- there's
this really strong, somewhat mysterious `presence' that is opposed to
the `Bad Guys', but can't interfere directly.  This presence has
agreed to help Lars (and others) defeat the great Evil, although Lars
may have to sacrifice himself in the end.

What I'd like to do, if it's ok with you, is have Lars start `playing
up' the religious mission bit more and more as time goes on.  He may
try to explain it to his friends at first (although that'll be tough
with the `exclusion' that's preventing him from saying certain
things), but I'd like to have it somewhat slowly develop, eventually
to the point where he's `preaching' to the bad guys about how they
should repent before they are destroyed.

The related game-mechanics I was think of were `Control Illumination'
and `Faith'.  Control Illumination is an electrokinet ability (first
level of photokinetics) that allows me to make it darker or brighter
in the area.  I'd use this (perhaps subconsciously) for the `holy
aura' effect.  Faith is a little stranger -- I don't really know if it
makes sense in the world or not, even.  Assuming that it does, I'd be
interested in spending some XP to increase my faith score, to go along
with the changes in character belief.
