Mermeia was a holographic fantasy woman who existed within virtual reality as an erotic entertainer for users of mind evaporators and holoprojectors. When accessed via the former device, she was a product of the user's deepest desires, and she appeared to them as created by their mind. On at least two occasions, she appeared as a slim woman with the features of a Human. Mermeia sang, danced, and flirted with those who accessed her, and the experience resulted in considerable pleasure for user and entertainer alike. Shortly after 0 BBY, Mermeia danced for an enthralled, holoprojector-using Twi'lek, and in 1 ABY, she sang the song "This Minute" to Attichitcuk, an elderly and excitable Wookiee who viewed her performance through a mind evaporator.
