Central Empire And Imperial Band

On Babur:

"Each Band had its own personality, which differed more from that of its fellow Bands than members of any did from each other."
-Poul Anderson, Mirkheim IN Anderson, Rise Of The Terran Empire (Riverdale, NY, 2011), pp. 1-291 AT p. 85.

The dominant Band is the Imperial Band of Sisema.

Baburites "...radiate variably at radio frequencies..." (ibid.) If they also receive, then they might be "telepathic":

"Perhaps in this way a part of tradition was not oral or written but directly perceived." (ibid.)

In three ways, the Baburites resemble James Blish's "Central Empire":

Bands with personalities;
(possibly) telepathic;
the application of the human concepts of empire and imperialism to an alien context.

In one respect, the Baburites possibly resemble Anderson's Didonians: a directly perceived tradition.
