Suppose someone had his dragonmark peeled off from his back and then raised (or simply survived the unpleasent experience), would he still be able to use his magic or would it be forever lost to him?
First of all...freakin' ouch. Is some sadist trying to make a dragonmarked tapestry? Eek.
Anyway, here is how I would rule it - mind you, I do not run an Eberron campaign nor do I consider myself an Eberron expert, so this is all my opinion. Dragonmarked heirs go beyond mere flesh and bone and no removal of said flesh will destroy that connection. Eventually, the dragonmarks will reappear on the flesh.
Anyone remember Grafts? Fiends, Aboleth, and Illithids are all capable of playing Frankenstein. Why couldn't some Daelkyr take off a Dragonmark and put it on whatever creature they wanted?
****SPOLIER FOR KEITH BAKERS NOVAL AHEAD (Cant remember its name)********
In Keith bakers novel a mind flayer does this to a Halfling with the mark of healing. It killed the halfling. or perhaps the halfling was dead when he did it. I cant remember. Its good though.
Since a character has to spend a feat to get dragonmarked powers, they should not lose the effects of that feat if their dragonmark is "stolen" from them. The dragonmark powers remain in you even if your mark is removed; the mark might even surface on its own accord elsewhere on your body.
This is not to say that some powerful magical effect can't come into being that can steal or surpress dragonmarks. It's just not enogh, I think, to just be able to cancel the feat (or feats) out by simply physically removing the mark.
This has been asked on the Eberron boards over at WotC. The answer from Keith Baker was pretty much the same as what James Jacobs said above, esp. about the mark reemerging elsewhere.
Well, in a way I am using it... but I think our ideas are different enough for Dungeon to accept both.
Ahh, I thought you were asking as a DM. My bad.

Oh no, my players wouldn't let me run an Eberron campagin. They are old school purists (which stands somewhat like a contradiction to the fact that they play a group of run-of-the-mill Orcs who raid humans and fight for honor.)
