A female Twi'Lek,one with long moss-green coloured hair,moss-green Lekku and caramel coloured skin with moss-green spots,she is a Mandolorian Bounty Hunter...again her armour is moss-green coloured...just like her eyes,and lekku...she can change into a cat.

So a play test of Order 66 was done..and the targets were The Elemental-Dancers, most were killed and the ones that remained were considered outlaws and to be killed on sight by Clones,the Jedi don't know about this incident.

Mamır was a Moss-Dancer.

Mamır died before the original trilogy of Star Wars movies began. 

Her death was caused by both of her optical nerves and all the blood vessels in her eyes exploding,which killed her in an instant.
