25:1.3

The number of servitals is prodigious, and more are being created all the time. They appear in groups of one thousand on the third moment following the assembly of the Master Spirits and the Supreme Power Directors at their joint area in the far northerly sector of Paradise. Every fourth servital is more physical in type than the others; that is, out of each thousand, seven hundred and fifty are apparently true to spirit type, but two hundred and fifty are semiphysical in nature. These fourth creatures are somewhat on the order of material beings (material in the Havona sense), resembling the physical power directors more than the Master Spirits.
