Naga Pasham*- snake -rope, rope used by Yama the god of death, or a rope with a noose. Naga pasham is first mentioned in the Ramayana.  During the battle between Rama and Ravana, Indrajit the son of Ravana uses an astra(weapon) with the Nagapasham on Lakshmana the brother of Rama and on Rama.  This causes them to go into coma.  Hanuman who goes in search of a herb to cure them brings back a whole mountain when he fails to recognize the correct herb.

The Brothers of Raghu vamsham*- These are Rama and Lakshmana who are the descendants of the Raghu Vamsha or the Raghu dynasty.

 

Kinnari has no link to The Ramayana.  I have just borrowed some ideas to weave into my story.
