Banished

The observers turn their backs on Kinslayer, separating her from them signifying her severance from the town.  With no place to return if she fails, she must set her sight forward toward her only hope–The Guardians.

 

Traditionally, this act is done for anyone leaving a clan to join the Guardians or to join another clan (usually for marriage.)  They can be celebratory affairs where the whole town shows to wish the person well, but they all end with everyone turning their back as the honoree exits the gate.
