See List of Undercity NPCs. Many think that Christoph Walker is the one who wrote the note in the quest Document from the Front that drops during the Scourge Invasion. The note reads: Dear Pamela, Tomorrow we make our stand in Andorhal, and I fear this will be my last letter to you, my love. The undead are unfatifued and we, I fear, are only human. We cannot hold against them. But fret not, for although we are sure to perish, our hope stays strong. The light will prevail!And my dearest, I take comfort knowing that, as those dark terrors storm our walls and crash over us, my last thoughts will not be of death. I will think of you in my arms and I will know peace at last.Christoph
