MONTFORT PALACE FORTRESS, 1133
KINGDOM OF THORGUNNA
THE SILVER DAGGER. The Montforts are monarchs of a Lycan lineage, but even though they have the supreme power of fast healing and speed—the fastest runners among the wolves' kin. Montforts' can’t withstand the natural poison of a silver dagger. Silver is the weakness of the werewolves in the entire universe, not only Montfort’s lineage. Even the de Lorris and Bethencourts. In fact, the entire descendants of King Gideon.
Therefore, if the silver dagger is not taken out of Ezra’s body on time. He will die not from the poison but because it was silver.
Not only does Ezra can't survive if the silver is embedded into his body far too long, but because Ezra is a non-shifter wolf. He does not possess the ability to heal his bodily injury
