Mayrla is a fragment of Lethe's mind - being the physical manifestation of attention.
She and her brother Amon D'Argent worked within primarily Baldur's Gate. Mayrla was an actress, singer, art model and spokesperson and Amon acted as her manager. Whilst not blood relatives, Mayrla was found on the doorstep of Amon's parents as a baby who adopted her and treated her as their own. Amon only discovered her true identity when he was involved with the Cult of the Green Eye.
After leaving her family home, she followed the party into the Synergy Group. The party are quite protective of her.
