Nel has been more at home in her dreams than in the waking world, and it almost came as no surprise -- to her at least -- that she could visit the dreams of others. She doesn't have particularly fine control of it, but she's told it's a rare ability, and there simply aren't many people who can train her, so for the moment, she's trying to teach herself.

Sample:
She wasn't sure when she'd drifted off, but she was relatively certain she was still in class, head drooping onto her keyboard. The teachers had stopped trying to wake her, though, and her grades hadn't suffered too much.

She blinked out at the dark landscape, testing her footing. Sometimes there wasn't any footing at all, and she fell right through, but this time there was, even if it was a little spongy. And a little slimy, she noted, bending to touch the ground.

Gross.

She straightened, wiping her fingers on her uniform tunic and launched herself gently into the air. She always preferred to fly in dreams. It was faster -- and frequently helped her avoid ground-based hazards. Though it did leave her vulnerable to air-based hazards ...

She scanned the horizon, then shrugged and floated forward, only to collide with what felt for all the world like a brick wall.

"Ow!" She recoiled, rubbing her nose, then felt along the barrier, frowning when she reached a corner and found a wall to her left as well. Scowling, she flew higher, hands carefully extended, and felt her fingers scrap an invisible ceiling as well. She cursed, trying the only two directions she hadn't yet, and found herself well and truly trapped.

A soft chuckle echoed out of the darkness nearby. "Well -- let's have a look at you."

"Who are you?" she snapped. "Let me out!"

No one came into view, though the voice id sound a little closer when it spoke again. "Hm ... you're not a race that's ever showed this particular talent before -- I wonder how that came to be."

She looked blank for a moment. "Yes, we have. My people have tales of dreamwalkers. I'm not the first."

The voice tutted, sounding closer still. "Dreamwalkers yes, but dreamwalkers of your kind?"

"Um ... they didn't really say ..."

"Well, perhaps I'm misinformed, but I doubt it." The air in front of her shifted, and a slender figure emerged from it, shaped vaguely like her -- two arms, two legs -- but with none of the racial markings that her people were born with. "My name is -- well, you can call me Lessa. It's probably simpler that way."

Nel spent a moment staring at her, a frown tugging her lips. "So -- who are you, then?" she finally repeated her question.

"I've come to teach you the finer points of walking dreams," she said. "I've been watching you for some time, and you have a fair amount of talent, but raw talent needs refinement. In the simplest terms, Nel'toleth, I'm your tutor."
