Prolix - I do appreciate your criticisms, as they are well thought-out and certainly polite enough.
(I do not see any 'flames' here myself)
As for your example, my response would be to take out a gang-member and steal his gun, since nowhere is it specified that he does not have one.

That is what I am doing - expanding on lore with my own ideas, using what information is available to me. And while I am not about to toot my own horn, I will say that with the exception of the Etherwights' existence itself, I
have stayed well within Settings bounds. Its creation, habits, and so-forth are all very explicable in-game according to what knowledge we've been given thus far - which is a fair sight more than most of the so-called 'outlandish' chars can claim (at least that I've seen). Regarding your last comment, I did not run this by a GM because I saw no particular need to - doing so makes it a GM event in my eyes, not mine. So to sum up, just because the wraith itself is pushing Settings (and I never claimed it didn't - quite the contrary), the use and application of such is certainly within bounds.
On the note of Xathen himself and claims of 'uberness' - please read through the RP threads a bit. He has unique abilities, true, but he is FAR from uber, and I have never played him as such (possibly why there hasn't been a larger faction of people screaming for my hide).
With regard to Etherwight purpose and origin, they drain life energy (ie, the soul), and so victims normally die a true death, with only ash remaining. This is why they are regarded as unholy by Dakkru followers and the Goddess herself - their method of feeding denies the Dark Crystal its fuel. And yet, despite this, I have not yet used him to drain ANY player to the point of permanent death, and have only seriously considered it once. In fact, if you wish to tear my wraith to pieces, I suppose it's best if you are given the full readout on him. Been meaning to make it public knowledge through RP, but since this discussion has grown a bit more than I expected it to...
