To answer your question on whether or not Lyrisa would recognize the emblem, yes, yes she would (successful Knowledge Roll)

To answer if he recognizes the Scribes (who are known to be a scholastic order by the way, magic isn't really considered to be a good thing in this world, so those who practice it do so [i]secretly[/i] even though those who just practice Arcane Craft know it isn't evil and that it is Sorcery that is). 

Leifr... would not recognize the scribe emblem (cause you know.. poor knowledge roll).
