It's nothing to do with the Sith, Rand, but you have heard of this before- really as a point of historical interest.
The Force always exosted, of course, although discussions of how it was before the eays of space flight are many and varied.
But some primitive cultures used the Force in combination with primitive and superstitious ways- and this is one way- Rune casting.
Basically the rune casting is a superstitoious rite used to determine the future; the arrangement, direction and even timing of the way the objects used fall to the floor give indications as to the answers thr caster desires; at first you have to cross referenc eeverything in a book or some other reference source, but the more practised you get the more you remember it all.
Now, that's all superstitious gumf, but combine it with the Force and it is different,. The Force gives genuine inishgt into the future, and what happens then is that when you cast the runes you sub-consciously cast them in a way that means they accurately reflect the truth the Force is giving you.
Gallador- you've actually heard of some places that still use such techniques. Interesting...
Gallador has Jedi Lore specialty and he would one of the first to speak if his player was offline. And Foresight for him, please!
"Ha, Lady Adelmo, we meet at last! Your appearance is not surprise to me, for the Force itself spoke to me on things to come! Long enough we have suffered idly on this pathetic world, wasting our destiny!" He wonders for a moment, his eyes burning with dark focus.
"Mighty are the Jedi, but lost in their cowardice stil! They limit themselves only to certain aspects of the Force, abandoming the great power that emotions bring! But they are right that mastering the Force entire without being consumed is trully a mighty task. Once I thought Rand is the true Master of the Force and is enough to lead us to greatness. But I was wrong, and now we are broken group, lacking focus and guidance." -He comes closer to the Lady.
"But you, Lady Adelmo, seem to be much more, I can sense your terryfying power and others follow your will. Perhaps you are the true Master that understands the power of the Force, and its deepest secrets. Tell me, are you one of those that are known as the Sith?"
