Maharet has been awake long enough now that she might have encountered some, or been previously associated with those before her slumber. I didn't specify an exact date of when she went into "hiding" and such so it's easier to work around for if people know her and all those bitty details. The wonders of plot work and time lines, heh. Maharet is "associated" with the Nyctari at present, being an ancient vampire and all that [and having woke her up] - etcetera, etcetera.
