My theory: You are a descendant of the escaped witches, the other vanished family had a mixed reputation because they were unethical doctors...such bird masks were common for medicus in the renaissance, so i guess your dream friend is from that family...and van horn is either the bad guy that plays the fragile cripple or he is the last one that keeps the corruption away and becomes weaker while the corruption becomes stronger.
After some Thought, I am Revising My Theory that "Ghost Friend" is NOT a Constantins.
Our "Spirit Friend" Maybe in fact Dr. Corvux. Wanting to Set Things Right! Saving his 'Beloved' Town & people.
Constantin's May Actually have been BAD; responsible for the "Corruption" curse on town.
The 'Curse' May have Always been here. Lisa's recent actions may have just been the catalyst to set into motion. ??
A Long time ago, possibly even Generations, the 3 Families lived in Europe. For Whatever Reason, IT was necessary to leave.
All three families had wealth, but Not enough on their own. It was the Van Horn's and Corvuxes working together; The Constantin's should have saw this coming but was desperate as well to leave.
Reaching an agreement, Constantin's paid for passage on a ship, to their New Home, in return for "Favor" when they reached their destination. And the Town of Solomon Falls was founded.
But as Time passed, the Van Horn's and Corvuxes refused to 'pay debt owed'.
As Like Any Town/City or Country there was a Power struggle for "Alpha leader". The Van Horn's were wealthy and had the most Influence;
The Corvux's were wealthy as well, and religious/spiritual. The Constantin's had little wealth (after the sea voyage, and the betrayal) and their practice of Magic.
Now we got the equivalent of "Hatfields & McCoys". Van Horn & Corvuxes siding against Constantin's.
Dr. Corvux declared the Constantin's guilty of being "Witches"*; the enforcement of Van Horn's Captured & burned Any Constantin they could find.
Driving the remaining survivors OUT Of Town. Dr. Corvux was then, responsible the funding and Building of the Church.
That Bible was possibly the property of Dr. Corvux, himself.
* It was reported, during this time, that Dr. Corvux's only child/son was killed in a "hunting accident". (Was it Really an accident?).
- a conclusion, that possibly Corvux's son, and a Constantin daughter had been meeting secretly, and were intimately close.
Or maybe the son was caught trespassing on Constantin property, where he had No business being.
It was never determined If he (the son) was there of his own volition or under orders.
It Is also unknown If Dr. Corvux's wife had passed away from 'natural causes' before, or after the death of their son.
After an Outbreak of the plague, Dr. Corvux's death soon followed.
Now, combining Both of our theories. Wouldn't it be Odd If Our MC IS an Ancestor of an 'unwelcomed Union'
between Corvux's Son and a Constantin "witch" daughter.
That is Why Our MC Is tied to This Town & its Curse. It is kinda up to her to Save them, and herself.
