The waxen seal was marked with "E".

[Erzsebet]

It was a simple letter, written in a steady hand, that the priestess left for the Grim:

To the pursuers of peace -

Many times in the past I have stood beside you, from the
darkness of Karazhan's chambers to more recently within
Ulduar's halls.  It has always been a great honor to work
alongside you, and now that my time upon the Mutiny has
drawn to a close, I now ask to be admitted within your
fold.  I await your word.

-- Erzsebet
