Induction into the Grey Council is a very ritualistic process. The Minbari take great pride in performing religous ceremonies to the utmost of their abilites. Of particular importance are the words spoken at the ceremony...
"Why do you come here, Delenn?"
"I come to serve."
"Who do you serve?"
"I serve the truth."
"What is the truth?"
"That we are one people, one voice."
"Will you follow me into fire? Will you follow me into darkness? Will you follow me into death?"
"I am become Grey. I stand between the darkness and the light, between the candle and the star."
