Limstella is a morph, an artificial human, created by Nergal. She is what Nergal claims to be “perfect power and perfect beauty”. As a morph, Limstella has no emotions whatsoever and exists to carry out any and all of Nergal’s tasks. Limstella seems indifferent to almost everything, even her own death, at which point she remarks that she feels 'sorrow', but acknowledges that this emotion is artificial.

Her voice should be medium to medium-low.

Limstella is not human and does not possess much emotion, if any. Honestly, just sound as monotone and dead as possible. Although she is referred to with female pronouns and uses the female sage model, Limstella is a morph and thus genderless. A feminine or slightly more androgynous voice could both work for her.
