We had the same question in our group. I gave it some thought, and would like to propose the following guide. It is inspired by common astrology, and how Morrowind handled star signs (e.g.
Those born under the sign of the Steed are impatient and always hurrying from one place to another. – 25 point bonus to Speed"). The suggestions themselves are based on the description of the Icons themselves, and their associated Traits.
"Acting in accordance with your Icon" would mean showing an appropriate (and noticeable) behavior trait (positive or negative) sometime during the session. HOWEVER, i
t is certainly not intended to pigeonhole character traits and personality. Rather, it should be seen as certain tendencies - and perhaps a useful baseline from which to build your character's personality.
