Return to Magistrate Solomon with Lord Ebonlocke's letter of response.
If I did not know Magistrate Solomon personally, I would say the man has gone mad. Send the Night Watch to Lakeshire because Stormwind refuses aid? The Night Watch was formed because Stormwind left us when this foul magic seeped into the land. If I sent my Night Watch, this town would be overrun by evil before the guards even reached the forest's edge.
Take this letter of response to your Master in Lakeshire.
