La Ville-Lumière
Order Conquers The Darkness
Rank: C
Type: Anti-Secrecy
As Parisian chief of police, Assassin sought to tackle the rampant problem of crime in the city streets. During the night when darkness concealed their detestable deeds criminals were free to rob and murder innocent citizens with impunity. By instituting the first widespread system of illumination across Paris Assassin banished that darkness, replacing it with the light of law and order. His efforts as well as lowering crime earned Paris the awe of the world, gaining the iconic epithet
"City of Lights".
Assassin's feats of illuminating Paris- as well as his favor from the "Sun-King" Louis XIV form the basis for this Noble Phantasm. Upon invoking its true name he can manifest "lanterns"- floating globes of light formed from his own magical energy. These "lanterns" serve as Assassin's eyes and ears, passively collecting data from everything that goes on around them. By merely touching an orb Assassin can display and peruse the information captured by it, much like a police-report.
Being first and foremost a Noble Phantasm of information-gathering
La Ville-Lumière normally has no offensive applications. However representing the severe punishments Assassin imposed on anyone who willfully destroyed his lanterns, any attempt to damage or remove the orbs will trigger an automatic defense-mechanism, blasting the offender with a bolt of solar light. This counter-attack is tailored to the strength of the attacker, so for an ordinary human it'd just knock them back and singe flesh while a Servant would receive the full destructive power of a C-ranked Noble Phantasm. The orbs themselves are still rather fragile though so aside from this defense a single regular attack can destroy them.
Chambre Ardente
Judgment Of Sorcery And Poisoning
Rank: B
Type: Anti-Thaumaturgy
A Noble Phantasm crystallizing Assassin's act of re-establishing the
Chambre Ardente
Burning Court
to judge cases of poisoning and witchcraft following the Affair of the Poisons. However it was abolished only two years later as the king wished to avoid the scandal of having such shocking crimes brought to light, to which Assassin said
"The enormity of their crimes proves their safeguard".
Invoking the true name Assassin establishes a Bounded Field extending for thirty meters around him that enforces the concept "rejection of
". Within it, anyone attempting to cast Magecraft is found "guilty" and punished by flames igniting within their Magic Circuits, burning them from the inside-out. This doesn't truly make Magecraft impossible to cast but damages the target as long as they continue to do so and inflicts debilitating pain that scales with the amount of Mana they pump through their Circuits. Should they persist practicing their odious craft, the flames may consume the Mage's body entirely and reduce them to ash.
This Noble Phantasm gives Assassin an advantage against Caster-Class Servants, shutting off their primary means to attack and defend. However the Bounded Field expends a fairly high amount of Mana to maintain so Assassin can only keep it active for five minutes most of the time. Furthermore practitioners of Divine Words (who lack Magic Circuits to target) or Sacraments drawing from the Catholic faith (as Assassin doesn't consider them to be "heretical") are unaffected by this ability.
