Niki Jemisin

Niki Jemisin is a Cascadian musician and singer and a minor character in Tacoma. She appears on a poster for a Bessie Smith Tribute Tour that took place in both the Cascadia-First Nations and Californio-America in 2086, which is found in the personal quarters of E.V. St. James—who appears to be a fan. While she does not make any other appearances in Tacoma, a scrap of the lyrics of her song "Last Fall" from the album Picturecards can be seen on the Steam trading card for E.V. St. James.

Picturecards
A Niki Jemisin album, number unknown. While it never appears or is referenced in Tacoma the Jemisin song "Last Fall" is accredited to this album.

"Last Fall"

You placed a leaf

In a flower vase

The day's last light

Caressing your face

This is the way you were when I last saw you

An empty room

Without a sound

A memory

Of the sun going down

This is the moment that I live in without you

Behind the Scenes
Her name is likely a reference to science fiction writer N.K. Jemisin, and may also be a reference to Mae Jemison, the first black woman in space. A book on Mae Jemison can even be found aboard Lunar Transfer Station Tacoma.
