Trisa M. Reyne

A famous strategist, tactician, and immortal military genius.

In Rosalind's Orphanarium
She is twelve in said thread, and a good deal more boring. She is known as "Frankenbaby" due to her immortality.

In Steampunk
She is an adult, and had a job as the local mortician until her husband Arthur was brutally murdered in her shop.

In Quarantine
She goes by T. M. Rain, mostly because she thinks it sounds cool. She may or may not actually be on the run from someone or something. She carries SCaDOS around in a USB, so obviously one or both is travelling through time.

Additional Information
She is inexplicably immortal due to her mother having been killed before she was born.
