In Blood Royal, you'll get a taste of Nexus Echo. It was employed a bit in Blood Domination, it just wasn't completely evident. It is mentioned in Blood Royal, but nobody ever explains how it works. So I thought I'd give you the facts now, only I'd let another character explain it. (hint: it's not Lissa, but Kiarra)
"Nexus Echo is an ancient trick the Larentii devised, to listen for key words, names and phrases. If Pheligar is employing Nexus Echo and his name is mentioned—he knows it. The trouble is, he'll never bother to explain how it works, he'll just fold his long blue arms over his chest and pretend you didn't ask. Therefore, I'll explain it as best I can.
This is how Nexus Echo works: imagine the entire planet is a lake. Now, imagine that someone places an invisible net over that lake. It doesn't sink—it floats on the surface. With me so far? The net is tuned to certain words, phrases or names, spoken by certain people. Any time any of those words are spoken by these people, it's like dropping a pebble into the lake. The pebble causes ripples, which make the invisible net bounce. The net caster has an ear tuned to that net. He knows when the ripples come and he can go in an instant if he feels his presence is warranted. Is it nosy in the extreme? Sometimes. But then being nosy means nothing to the Larentii; they are never worried or embarrassed over any information, and think the rest of us are just being silly over the whole thing. I must admit, however, that many of the Saa Thalarr and their healers, along with a few other powerful races, have adopted Nexus Echo and employ it at times. Is it a logistical nightmare? The simple answer is yes, unless you are Larentii."
Okay, it's me again. And on another note—I love the Larentii. I think every woman should have access to one, just for the trilling alone. (I'll explain that, someday) And while I love Pheligar, he's my second favorite Larentii. My favorite Larentii is his son, Renegar. Also a tale for another day. Going back to work, now. November 15th is coming.
