What you know
Book 3: The Nonborn King
- Ch 1The invaders' sigma force-field is a mirrored hemisphere about fifteen meters across that no Tanu weapon or psychocreative energy can penetrate.
Book 4: The Adversary
- Ch 12A sigma field is thought to block Marc's d-jumping but acts as a beacon to long-distance farsensors, so Elizabeth won't use it for the redaction.
- Ch 26The sigma-field shielding the labs, brought from Ocala, is rated proof against psychoenergetic attack to the five-hundredth degree, and passes only minds on file.
- Ch 29The sigma-field, powered by an SR-35 generator and two SR-15s, has psychoenergetic strength over 900; Aiken says no Pliocene weapon can breach it.
- Ch 29Only Aiken can activate the airlock of the sigma-field around Castle Gateway.
