Well this is a few deities based off alignment to start
did you know there are 9 alignments and 9 schools???
From here ypu could create a story I think Ravaonna and Gracenys are femaleCode:[B]DIETY ALIGNMENT DESCRPITION [/B] Davendithas LG protector,life,guardians Gracenys NG healing,creation,community Alidiana CG retribution,self-defense,discipline Fruian LN reason,intellect,study Jamven N fate,destiny,vigilance Quimorel CN elements,planes travel Zinnastine LE trickster,guile,secerts Ravaonna NE murder,greed,undeath Hortumal CE tryanny,destruction,conflict
and sisters but, complete opposites. Davendithas opposes Hortumal at every turn
and so forth. Hope this is a good start for you.
One thing I saw with HM's pantheon confused me, and I dunno where else to mention this. Tyranny means oppression, which implies order, which in D&D means 'Law'... which is opposite Tryanny... Trickery is more chaotic from what I understand...
