SHAR
Shar is also known as the Mistress of the Night, the Lady of Loss and the Nightsinger.
Loss is the nature of Shar. One of the Dark gods, she is a deeply twisted preverse being of ineffable evil and endless petty hatred and jealousy. She rules over pains hidden and not forgotten.
She can always percieve every being, object and act performed within darkness.
She is the mortal enemy of Selune and battles her ceaselessly on mny planes through mortal creatures and servitor creatures.
Dark followers (the faithful of Shar) are instructed to reveal secrets only to fellow faithful and to never follow hope or turn to promises of success. They should quench the light of the moon (the faithful of Selune and their holdings, deeds and magic) whenever they find it and hide from it when they cannot prevail. Above all, the dark should be a time to act, not to wait.
The church of Shar sponsors a special order of clergy called the Dark Justicars. To gain membership one must have killed a member of the clergy of Selune.
Her allies are now dead and her foes are Selune and Lathander.
