"That's fine, the language isn't anything like a well-kept secret. I haven't bothered to learn it because writing spells in English works just as well, but I could if I wanted and so could you."

She picks up the second rock. The first line is slightly modified to accommodate the syllable change:

"Kas Petaal, it's your light I call,
Brightness for me to see by,
Shine from that which I hold."

This rock does, to all appearances, absolutely nothing.

She puts it down and repeats the procedure:

"Evisa Iannakara's light, come..." (The rock shines, like a firefly, faintly bluish and organic in character, not nearly as bright as the first.)

"Yambe Akka's light I call..." (The rock is speckled with faint yet attractive dots of starry light.)

"Farakhel Nimah's light, come here..." (The rock behaves like the waxing moon, a sliver of glow expanding until it covers the rest of the rock - and then it goes out.)

"Amariah Lytess's light is summoned..." (The rock lights up with gentle silvery moonglow and holds steady.)

"Memma Belir's light I call..." (This one is the reverse of Farakhel Nimah's; it starts like Amariah Lytess's and then slides into darkness.)
