You are The Weeping Angels,
The Great Alliance aligned.
The Weeping Angels were an extremely powerful species of quantum-locked humanoids (sufficient observation changes the thing being observed), so called because their unique nature necessitated that they often covered their faces with their hands to prevent trapping each other in petrified form for eternity by looking at one another.
This gave the Weeping Angels their distinct "weeping" appearance.
They were known for being "kind" murderous psychopaths, eradicating their victims "mercifully" by dropping them into the past and letting them live out their full lives, just in a different time period.
This, in turn, allowed them to live off the remaining time energy of the victim's life.
However, when this potential energy paled in comparison to an alternative power source to feed on, the Angels were known to kill by other means, such as snapping their victims' necks.
You are a Tracker [2-shot] and Executioner [1-shot].
At night you may choose a player and you will be told who they visited.
During the dayphase, if the lynch vote on any player reaches half or more of the number required to be successful, you may elect to instantly complete the lynch on this player.
This execution action must be PM'd to me for it to be considered - posting in-thread or in your QT will not result in the role being used.
You win when The Great Alliance controls the lynch vote (ie when noone else can win).
