i presume that 魔神 include all those 古魔 demon、魔鬼devil、神灵god. so how about 'magical beings' for 魔神? or maybe just good old pinyin? for reference: 地下世界传说之中是第三术士皇朝魔神皇朝的时代一些从人类术士手中逃脱的魔神以无上神通借助一件绝世秘宝开辟而成的一个反抗者总部。 无数企图反抗人类的古魔、魔鬼、神灵汇聚在这反抗者总部与人类术士激战了数千年。最终所有的反抗者统统都被人类术士镇压、封印、灭杀。 Thanks Bye, have a beautiful time
i already have 恶魔 as fiend... and i feel like 魔神 is the general name given to all those magical beings. therefore, fiendgod sounds weird
神灵 mean spiritual god and 魔神 mean demon god or devil god, and it should be a title of the supreme existence among demon or devil
In CN fantasy 魔 is often considered as a race, while 神 is often considered as a status that can be achieved by cultivation/training. So 魔神 often means the top leaders / strongest people of the 魔 race, like "Russian marshal".
