Orka Fyfån
Orka Fyfån (/'fif(ə)n̩/ THIEF-nn) was a Häftiägen comic in the Underworld who doubled as an informant and occasional operator in the Dark Network in the era of BHH, and Charlotte's fleeting key in BHH. Orka was raised in the usual Häftiägen way, being made to train as an entertainer for other Central Galactic Congress species, and she was successful enough to be allowed to specialise, choosing to become a stand-up comic. Rather than working in the CGC, Orka was drawn to the Underworld. She used her position as a travelling entertainer to establish herself as a "Dark Network comedian" who was accessible off-stage as a woman who knew things.
Orka also became an occasional Dark Network operator, arguably even a part-time derata. As a fleeting key, she always ended up associated with the Fourth Army, though this usually came about through her attacking the group or being taken prisoner. It was established that she and Ciarraí Teagwyn Kavanah had a prior relationship and had gone up against one another in derareti before — Ciarraí's take away from these experiences was that "I can handle Orka", though he seemed to regard her as his equal, whereas she expected him to take "you’ve seen what I can do, and I'll do it to you" as a credible threat and assumed his experience of her meant "you’d rather not be on the bad side of me".
