A man who is on the run or otherwise trying not to be recognized will often grow a beard as part of his attempt at concealment. The inversion — where a heavily bearded character shaves for similar reasons — is also relatively common, doubling as an Important Haircut.
If the character in hiding is ashamed of what he's done, it may also count as a Beard of Sorrow.
Wig, Dress, Accent is another variation on the theme.
Not to be confused with Growing the Beard, which is figurative instead of literally growing a beard.

(As Zakath is the Emperor of the largest nation in the world, his face is on almost every coin in Mallorea, which would tend to hinder attempts at stealth.)
