I hate when people do that. Can't people admit there is a mistake, instead of mocking the one who pointed it.
Only if it actually is a mistake.
Indeed. [Points I wasn't aware of but still agree with]
Well, I guess if Nath said it needed something else (so finally, you agree with him), it was because the spell may have been described as the one used by Sirrurg.
And actually, the fact that it could have been powered by Dragon Magic was not even the first idea of Aaron (who might be one of the guys in charge around, unless I am mistaken >that is to say, one of the guys who could have one of the most "official" and rule fitting explanations).
Instead, we have been offered Ritual Spellcasting, which is ruled in such way that it needs tremendous amounts of efforts to pull such a trick.
Conclusion; the fact that we are not bluntly said "it is Dragon. Nuff'" or "plot device", means that they had no idea, and that they could fit it in the rules.
It is ok, errare humanum est (actually, it could have been helped with a little research like the fact of using corps names without link to their background, but ok, SR love is huge).
And then, we have the "smart" reaction of Mystic which made me react.
Do you understand my meaning now?
