While interacting with Oakley he sent out a contact form on the obscurum.space website:
Do you have any information about the state of Aeternus's projects?
For now, please have any individuals concerned about Aeternus fill out the form at https://obscurum.space/contact.
I will keep on trying to gather intel about the current state of projects and will send out an update once I have a better idea of the state of things, and the resources available.Paula was one of the people involved with the original discovery that led to Aeternus Center and others. Do you have a means to contact Paula?

- the letter
- A polaroid (showing a D&D player handbook edition 3.5)
- A card: 6 of heats with letter "U"
- A coin
Solution
The polaroid which showed the D&D Player Handbook was the important hint.
There is a D&D spell Zone of TRUTH which can be used for the overlays
We really struggled to make a perfect overlay because it seems there a different versions of the book available. Oakley sent us the PDF which has the correct layout:
This led to the following solution:
"Within Tower"
"Speak the words"
"Override"
"Inventory"
which hints towards a Backdoor in the Discord Simulation
The cards seem to be part of another Cards Puzzle
More letters
Besides the four puzzle letters, people recieved letters with 4 more cards
