Ikalla

Madam Ikalla was minor vampire royalty in the Dark Times. Following the Kotturuh crisis, she received the energies of the Gates of Death from Inyit when she passed, turning Ikalla into the "Last of the Kotturuh, but changed".

Biography
Ikalla was aboard the Coffin Ship that the Ninth Doctor helped liberate from the Great Vampires. During the Battle of Mordeela, she commanded the Vampire forces. (PROSE: All Flesh is Grass)

She travelled with the Doctor to Parvanna, where they were hunted by an invisible creature, which the Doctor held off by setting a sonic stake alight, until they could be rescued. (COMIC: Tales of the Dark Times)

Ikalla escaped the Coffin Ship when it was attacked by the Dalek Time Squad, but was captured by the Death Brokers and brought to Entranxis. They showed her to the Tenth Doctor when he came to the Brokers asking for weapons and the Eighth and Ninth Doctors arrived, having been tracking their tenth incarnation. The Daleks attacked Entranxis to capture her, seeking a Vampire for their biological experiments, and she escaped with the Ninth Doctor. She accompanied him when he went in search of the Kotturuh to try to help them, eventually meeting Inyit on Birinji. The Doctor left her to look after Inyit whilst he went with his other selves to defend Gallifrey from the Time Squad. Ikalla witnessed Inyit's final judgement on the Dalek Symbiont and Inyit transferred some of her energies into Ikalla.

When the Free Undead settled on Birinji, Ikalla became their scion, liberating them from the fates of the Great Ones who had turned them. (PROSE: All Flesh is Grass)
