((ooh following, what's this about?))

They had something to do. Possibly.
Kiaan/Kiaane is just walking along towards the outer borders/training area with various things in hand. One, a book. Two, a zhua. Three, a "water bottle" (basically a water capsule) stuffed with cold and completely bitter coffee to the brim. Like usual they have zero awareness of what's nearby or is just ignoring everything.

Kiaane either doesn't notice or doesn't care. They continue on, at one point starting to swing the zhua and then stopping just about as soon as they realize the motion.

Kiaane wasn't going anywhere too special. Well, they were going to the place within the premises that they had deemed appropriate for training purposes. After a presumable time-skip where their steady but sure gait proves to be able for the stalker-child to be able to follow up with, Kiaane set the cup and book down on a table-like structure nearby, never having turned their head around even once.

The question is how he does that without being noticed since Kiaane's still in front of the table. Y'know, just chilling with a deadly tool in a hand and an uncapped coffee capsule in the other. Then they just casually take it up again and drink out of it. The coffee's half gone in like a split second. And yes, this is like their third cup in this hour. And then they cap it again, set it down with a thonk, and turn around to presumably train a bit.

Well, Kiaane's not the type to really start doing anything impressive or anything. If they're aware of a spectator, they don't show it in their efforts. In fact, the heads of the guild could be under that table and they'd still be acting the way they were. In any case, they reached the relative middle of the flat grounds before stopping. Extending a hand, they pointed at the air, drawing a vague circle-like shape without speaking. After only a moment, the circle blared to life, extending slightly in radius before pulsing but changing no longer in any other way.

They lowered their arm, but the circle didn't vanish. However, as soon as they moved their other arm to the side, it jerked to life. In a huge motion, the shape flipped around horizontally, but not completely, phasing through Kiaane before maintaining a parallel stance to the ground.

Kiaane definitely heard that, but they don't care much. Rather, they just continued on. In reality, it was only just a magical circle, so with a few more moments and a sequence of 3 flashes, a sphere of light emerged, then distorted and grew into what appeared to be a long and thin object still glowing in the color of the fading circle.

They really haven't noticed that before.
In any case, the circle fades out completely and they grasp the long and thin object, which appears to be a very simple staff. No particular decorations or anything.
As per the usual usual, if Martin doesn't speak up, Kiaane's just going to continue ignoring the fact there's a spectator.

Fortunately for him, Kiaane doesn't react harshly. They kind of just turn and gaze at him neutrally. 

"I see," they did finally say at some point.

"Magic," they answered. No irony. No humor. Just the statement.

"A magic circle is the means, not the result," they answered directly.

"Not in this instance." 

Kiaane really didn't like talking about themselves. As if stunned by all the questions, they just said, "Yes."

If Kiaane's mind worked in slang, it probably would be thinking something like 'y u make me talk so much???'
They weren't noticeably struggling in terms of facial expressions (they didn't make weird expressions while thinking or anything), but the huge gap that's not answering questions is probably indicative enough.
