The Union of the Hideously and Improbably Deformed have an initiation ceremony for new members, which entails fixing a veil over their face.

The phrase 'a Type and a Symbol' is a reference to Nathaniel Hawthorne's story The Minister's Black Veil:

Know, then, this veil is a type and a symbol, and I am bound to wear it ever, both in light and darkness, in solitude and before the gaze of multitudes, and as with strangers, so with my familiar friends.
