Question [CN] Need help with a sentence and a term

sentence: 也是黑暗精灵神系里面的一尊神灵弓箭少女传下的箭术。
term: 神系

other instances of the term being used:
兽人神系、精灵神系这两大神系也只有联手起来，才能够与萨利雅神系、或者泰坦神系抗衡。

若非萨利雅神系、泰坦神系这两大人类神系之间乃是死敌关系，双方争斗不休，结下了无数死仇。而且还有中立神系、黑暗神系、海洋神系、巨人神系、巨龙神系等诸多神系在一旁掣肘，整个费索位面根本没有其他非人神系存在的余地。

Thanks
Bye, have a beautiful time.

 

Rough Translation:
Term: deities
Sentence: .....also an archery skill handed down by a divine spirit arrow goddess from the dark elves deities.

*IMO, this is more about naming convention. You may replace the underlined with other names that have similar meanings.

 

I translated this 神裔 as deity
how about belief system?

 

I will recommend mythos then.

 

IMO, "belief system" doesn't sound fantastic. If you have chosen deity for 神裔, I recommend theogony for 神系. Then 黑暗精灵神系 may be "Dark Elves Theogony"

 

uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
that sounds really cool
