Whole OOC post:
Wow, thank you all for your participation; I seem to have struck a nerve or something like that ;-)
By the way, I've begun with this post to outline the apprentice's speeches with comic sans, in case you'll need an incentive to do him harm. (no, you surely do not need an incentive for that.) Actually, I think it to be an amusing contrast to see world domination or revenge plans in comic sans.
Now, for some questions/answers:
He didn't bind us properly. Kill him and begin to take note of our surroundings.
I hope to have answered it better with the post above. Basically, as I imagine it, all of that stuff is done during the summoning. To summon a demon you make a pentagram, and summon him. The pentagram contains, properly drawn, runes to summon the demon (together with the incantations), bind him, make him not hurt you directly, make him do your bidding, and to get rid of him. Like a fire and forget uhm... demon. Completely save if you word your task right, are experienced and don't make any mistakes.
I like to imagine we have no true form since we shapeshift so much. I dunno, it just feels right.
I agree with that. As a demon of trickery, you have no 'true' form, instead you can jump around as much as you'd like. Of course, if you'll like and describe it to me, I can do some kind of default form you'll take when no other is specified, and it isn't too dumb. For example, you could take the form of a yellow elephant (please don't take the form of a yellow elephant), and if you go to town I'll use a human form.
Oh, and OP did you get the idea somewhat from The Bartimaeus Series? The summoning and types of daemons seem slightly similar...
(First book in that series: http://en.wikipedia.org/wiki/The_Amulet_of_Samarkand)
Not directly, but partly. The types of demons I just pulled out of my sleeve (with some research a.k.a. clicking on links on the internet and a bit of 'That sounds logical'), and for the summoning I afterwards very much noticed that it was quite similar. Well, why not...
The main idea actually was from the 'Demonhood' forum game I read a couple of months ago, and which I plagiarized at least for the demon idea.
I'm all for killing him, but let's make him do a bit of stuff for us first. I continue with the crying plan, but should he release us we make him do a bunch of shit for us before killing him. After all, we are the demon of trickery. I assume at some point our powers are linked to the use of this tactic. Therefore, trick him as much as possible, then kill him when we are no longer able to get anything out of him. But patience is a virtue at this time. Besides, we still have to gauge his gullibility.
Your powers are linked to several factors. Tricking mortals definitely is one of the possibilities. Getting mortals to do your bidding, another. Getting mortals to worship you might be another. Maybe senseless killing could be one, maybe eating yellow elephants. You're new to this world, you don't know that well, yet. Just like you don't yet have access to your powers, as they are blocked by the pentagram. Once you're outside of it, you'll get them, though only in a weak form for now. They'll grow as you grow.
