Drider redux

Lolth eventually summons a drow house's matron mother to the Hadesweb for a test of faith and strength.  Those matron mothers that pass the test rise higher in the Spider Queen's favor:  they are transformed by Lolth into driders, the blessed image of Lolth. Those matron mothers that fail the test prove that they are unworthy to lead a drow house to Lolth's satisfaction.  They are stripped of their role as matron mothers and remain in the Hadesweb to spend an eternity serving Lolth, rather than leading her drow.  In this way, Lolth surrounds herself with powerful drow.

As the favored of Lolth, all driders enjoy considerable power and authority in drow society.  The drow believe that a drow house that does not have a drider for a matron mother is experiencing the displeasure of Lolth. Such houses face stigma and disdain from the greater drow community.
