What happened to NagRani who is Amrita's real mom

Hey,

triveni tried to kill amrita and nagrani came in front and died. in naglok the rule is that if you kill the nagrani you become the nagrani. thats why triveni is now the nagrani

once naagrani get killed not even naagmani will bring her back to life. she is gone for good so that new naagrani can rule..that is the law
