Is it a possibility for them to be triggered accidentally and/or by a third party?

It's not really explained anywhere.

I suppose I probably should've explained this better in the OP. Sometime between the ages of 10 to 18, the channeller will notice that, whenever they start feeling a certain intense emotion, they will start using their power. The emotion that brings out the power will be specific to each channeller. So for example, one character I have planned for the RP is someone who is very passionate and easily angered, and one moment when she got really angry, she suddenly created fire from her hands for the first time

Is it alright to make a "magical" item creator as one of the mentors? By that I mean items that hold innate power that non-channellers can even use?

Hmm. The problem with this is kind of the same problem as the mech thing, it ends up bringing a whole other aspect of the RP (that being magic) that has to be balanced and fit into the world

Could one's power feasibly manifest as some extra mechanical doodad on their body?

Continuing the item questions, could there be items powered by Mana/chakra/ki that help in battle/daily life?

It's hard to say for sure for both of these questions. I'll kinda have to read a character sheet that describes these abilities in more depth, we'll just have to wait for when I make the OOC (don't worry, it should be soon)
