you wanna ****** go right now
Alright lets do this
At the end of the oracle comic we see pa traveling between realities spitting herself to assassinate targets across dimensions and space. As she does her contracts, we see via her arcane that she becomes more ethereal and ghostly. As her physical form fades, we see her change to become more ghostly and faded from our realm.
Furthermore:
-Specter throws a dagger, like PA which slow the target
-Specter has a ability which deals additional damage to single targets
-specter has a passive which affects heros that attack her
-specter has the ability to cross long distances to instantly appear at her target.
FURTHERMORE
-specter has the same voice actor as PA, but reversed and echoed. When pa gets her arcana her voice echoes as well.
-THEY HAVE THE SAME VOICE LINES for several things. Also, the other voice lines are ones of confusion and apologies, and when she wins she claims she is finally able to go home

-specter has nearly the same weapon as pa but in a ghostly form held in the same way, offhand with one hand.
-both of their names start with the same letter and are very similar, as if it was remembered incorrectly or lost over time
-pa is the one sister of the veil that values her own name, and her own self. Specter is attempting to combine the diffrent versions of herself to find out who she is. Her identity is everything, just like PA.
AND THERE YOU GO.
