Severian was an unusual fellow, and his eidolon bulked up more quickly than

It's also possible that B, F & O didn't know everything about eidolons (2
of them being youngsters, and the other one a not very intelligent robot).

Eidolons must be able to acquire and store additional information after

otherwise interact.  The eidolon of Malrubius must have learned "The Key
to the Universe" at some point after being created, but before dissolving.
