Following the death of Ardant and the recovery of the Shroud, Gramática retreated to a top-secret facility to continue working on Project Phoenix without prying eyes. Even his fellow Templars, such as Laetitia England, were unaware of his exact location. Gramática did, however, send the coordinates to Berg, allowing him to deliver the Precursor box to his lab, which he hoped would help him better understand the Shroud. 
In October 2016, he was present during the induction of Simon Hathaway into the Inner Sanctum. Ten days later, Gramática sided with Rikkin against Hathaway when charges of treason were brought against their fellow Templar. However, only backed by Gramática, Kilkerman and Stearns, Rikkin had no choices but to drop the charges.
In March 2017, the Inner Sanctum invited the new Black Cross to a meeting in Quebec, during which Gramática was present. Displeased that he auto-proclamed himself their inquisitor, they threatened him and demanded to know his identity. The masked man responded that he came only as a courtesy, to inform them that he was investigating an hostile fifth column within the Order. After affirming his independance, the Black Cross dropped a smoke bomb and disappeared.
Reportedly, Álvaro is highly resistant to drugs, as he was barely affected when Violet da Costa put "enough tranquilizers in [his] coffee to knock out a whale".Despite this, he had to get his stomach pumped when he deliberately ingested a massive dose of pills while experimenting with the Shroud of Eden.
