Servant of Concealment is an angelic rank, and its authority — Concealment — makes the bearer one of the most inconvenient opponents in all of mysticism.
Concealment of the target — he puts the victim into a state that the outside world does not perceive at all: regardless of the target's will, it is as if they are erased with an eraser;
concealment of secrets — one can guess at what is hidden by the traces left behind, but as long as the knowledge remains under concealment, saying it aloud will not work;
reverse concealment — he removes the hiddenness from what was concealed;
concealed world — an entire region, hidden on its own, into which the target can simply be sealed;
concealment of everything else — identities, deeds, the content of conversations, and much more besides.
Hence the combat application: the Servant of Concealment secures the surprise of a strike almost guaranteed, and with the same authority he notices angels gathering beyond protected zones.
His former powers also grow: the Nightmare World now covers a large city, and from the mere presence of the bearer, Requiem brings utter peace all around.
The mythic form becomes complete: a huge eight-legged demonic wolf with six arms — four growing straight from the ribs.
The ritual of advancement to this rank looks modest, but is in essence cruel: one must sever everything that binds you to people.
