The Keth are a species created for this story, they appear in Act I and briefly at the beginning of Act II. They are on a civilian luxury ship that Rot Lop Fan saves. They are reptile like but that shouldn't effect the performance to much. These all being very small parts of one or two lines any one who auditions can likely be guaranteed a part. Improv is encouraged, if you can do multiple voices that don't sound alike then please go for it and you can have multiple parts.
These are the passenger's lines as they are being rushed into escape pods. There's an intense panic and it's chaotic. Fear should be in a lot of these lines. Feel free to improv other lines that fit the situation.
