"Try putting something into a mage dimension? That's the first thing I did with magic, and I didn't mean to and it isn't technically magic anyway, but just hold something in your hand and want to put it away, or hide it."

She flips a small knife into her hand, focusing on wanting to hide it away.

She feels the knife move in a direction she was not previously aware of existing.  It vanishes, but now that she is aware of the direction it went in, she can feel the connection, and could probably pull it back out.

Huh.

She tries that.

She gets the knife! She gets something else too.  Something that feels almost like a gust of wind and static electricity mixed together.  It swirls around her hand and her knife and then away, in Alistairs direction.

Alistair feels the mage energy hit him and grabs onto it, attaches it to a nearby plant.

"Awesome! Be more careful when pulling things out of your mage dimension in the future, you got some mage energy with it, and ambient mage energy can fuck things up."

"How do I control it, then?"

"For just pulling things out, make sure you concentrate more on the item and not on the connection to the mage dimension.  When actually pulling out mage energy, have an idea of what you want to do ahead of time, and as you pull it out try and tell it to do that thing, so that you direct it before you lose control of it- grabbing control of it once you've already lost it is harder than controlling it in the first place."

She nods, and tries to repeat the trick, this time only wanting the knife itself...

The knife appears in her hand! There is no sensation like wind and static this time.

Good.

Can she put the knife away even when she's not touching it?

Where does she put it to try this?

On the ground.

It does not go.

"Hm. Do I usually need to be holding it?"

"Yeah, usually.  It's possible to learn to do it from a distance but you have to practice.  Start by trying to put it away while touching it through something, like by putting it in a bag and touching it through the bag."

She tries putting it in her pocket, and touching it through that."

It won't go at first, but if she keeps trying for about 5 minutes eventually it will go.

She's pretty stubborn, fortunately.

Then she will be able to move things she is indirectly touching into her mage dimension!

"Cool! It seems like you got it! It should get easier the more you do it, but don't bet on being able to manage more distance while you're still working on this stage." Just to show off, he tosses a rock in the air and moves it to his mage dimension mid-air.

"I won't get too far ahead of myself."

"Well, we should probably keep moving.  You can practice as we walk.  If you don't care about sleeping in a house, I do have camping supplies with me." He hadn't mentioned it before, since he is visibly carrying very little, but since she knows he's a mage, there's no point in trying to arrange to sleep in someone's barn to hide that he brought stuff.

"I don't care, no."

Alistair will keep walking until close to sunset, at which point he will head away from the road and begin pulling out camping supplies and getting set up.

"We're enough in the middle of no where that it's probably not that safe to both sleep at the same time, do you want first watch or should I take it?" 

Alistair is so glad that he spent so much time reading fantasy adventure novels before he got dropped on this world.  It seemed like a waste of time at the time but now he gets to seem like he has any idea what he's doing.
