A 'wide' question, but to generalize:
Individuals who desire power, especially to destroy surroundings and status quo they detest, are given it by Shar.
A Sharran gains community and importance; they "matter" and are achieving things. Very attractive to "nobodies."

You've probably been asked this many times by now, but could you describe why people flock to Shar's worship, why they stay (both in the lower and upper echelons of her followers), and what their activities and goals entail?
