Mother Marise

Privileged few outside the Nightsisters ever get to meet the Nightmother, fewer less know her name. And few even within the Nightsisters even know that she is not actually the Nightmother.

Background
Mother Marise is in truth, an Immortal that has been in service to the Nightmother seemingly from the beginning. Working as the intermediary between the Enslaved Intelligence and the rest of the order. Her humanoid form also allowed her to teach the early members of the order.

It is unclear if Marise is her own person, or merely a puppet controlled by truth Nightmother. They never seem to meet, as to not draw attention to the true one's location, however they may be able to talk over some sort of Invader network.

She met with Ahmed Thrakul during the Seven Journeys.

Personality
Mother Marise is a cold and calculating individual, focused on the efficiency of the order. All work the Nightsisters do they consider for the greater good of Humanity, regardless the cost, and it is Marise that has instilled this in her 'children.'

Despite this, she can often give off a warm, motherly tone when she wants to.

Abilities and Notable Equipment
As the multi-thousand year old founder of the Nightsisters, Marise is likely the most deadly assassin on the planet. Her connection to the Nightmother has likely avoided the usual mental 'reset' that can happen with an Immortal.

Trivia

 * Marise was a figure introduced late in Gen1 Canon as part of Kaya Lem's backstory and the establishment of Dath.
 * The current depiction of her is actually a sort of reconciliation between the G1 and G2 natures of the Nightsisters.
