Morgana, known to her own kind as Sings Truly, was a Sphinxian treecat of the Bright Water Clan.

She was a memory singer, as well as one of the most important treecats in this species' history: after her brother Climbs Quickly became the first 'cat to bond with a human, she suggested bonding with humans as a policy for interacting with them successfully. Inter-species bonding became the treecats' standard strategy to cope with and learn from and about humans while concealing their true intelligence and abilities. (HHA1.1: ABF)

She soon became aquainted with her brother's human, Stephanie Harrington, who gave her the name 'Morgana'. Together with Lionheart, she made Harrington aid them in the capture of Tennessee Bolgeo, an off-world criminal who tried to kidnap treecats and sell them as pets. (SK1)

Towards the end of her life she advised Seeker of Dreams on his prospects for adopting a human, that resulted in him adopting a member of the Royal Family of Manticore. (HHA2.2: WPD)
