Dramatis Personnae
In reply to Lt (jg) William 'Fast Billy' Xelox (msg # 5):
Klaang is a Klingon diplomat, an emissary rather than an ambassador. He's a Klingon noble who's been assigned by Chancellor Martok to Dyson Base as an intermediary between the Empire, the Federation and the BortaSngan.
Dr. Kehlef is a Klingon geneticist assigned to work beneath him in conjunction with Federation geneticists on solving the resistance of the BortaSngan genotype to the century-old cure for the Augment virus.
Note that the IKS from the FASA Triangle books are, in my continuity, an offshoot of the self-proclaimed Fusion (Augment, or TOS-style) Klingons who closed their borders to the Empire in 2268 when the Empire released the Cure into their own populace. It is unknown whether the IKS also developed a resistance to the Cure, but they are decidedly hostile to the Cure. They are reclusive, forbidding their citizens all contact with the Empire, and with a shaky alliance with the Romulan Star Empire, a holdover from the alliance between the Empire and Star Empire of the late 2260's. With the current suspected Romulan involvement with the BortaSngan resistance, there is speculation at SFHQ and the Federation Council that the IKS may also be involved and inciting the resistance.
