Letter from A Son of Proteus to his Brethren in Egypt

Penned by the doppelganger that led the failed coup in Chrysopolis. Written in Egyptian hieroglyphics.

  Brothers!
  
  Too long have we lived in fear because we know not whether the pharaoh possesseth the eye 
  of Ra, or the Greek nail, or the shenanigans of Allah; let us now follow the example of the 
  Jews.  Here, where the trail went cold, there lieth a pleasant land filled to bursting with 
  human brains.  Might it be promised?
  
  Directions: Follow thou the river down.  Once out upon the father, travel around the horn 
  of the Hittites.  When the skin of the father narrows to a shout's range, turn right, and 
  there thou wilt see a crudely filled in harbor.  Thou wilt know me, of course; I will be 
  the one surrounded by smug humans who do wish to be assassinated.
  
  Bonus:  The traitor (his name is spelled in hieroglyphics here; three glyphs: a long tailed 
  bird? A crown? A scepter?) whom I, for one, was seeking before my stroke of luck, is said 
  to be nigh.  Let us divide him.

The message is signed, again in hieroglyphics, this time with four glyphs: A tortoise? A ship? A mountain? A feather or a leaf?
