Now I feel bad because the Hierophant of the Mur-Po is kind of immortal-ey, though being the ego-maniacal leader of the Mur-Po race he (it?) is basically the most taken-care-of and important person in the Ascendancy; also he is going insane from his body's rejection of cybernetic implants.
Hope that between that, espers, and insane kamikaze bioships I haven't gone too far! Though with whatever questionable tech I have I do try and counterbalance it with some pretty huge downsides. The first il-ship destroyed a moon and devastated a planet and are effectively uncontrollable and weak even now after over a century of further research. Powerful, but with some big-time disadvantages; and furthermore, they don't form a big part of the Mur-Po military (at least, not yet), and a big part of their usage comes from surprise. They're glass cannons, effectively.
Speaking of, would anyone have any interest in having some dealings with the Mur-Po at some point in the future?
