Petra is a young scientist working in Portia's Research Center alongside Merlin. Petra is fascinated by technology from the Old World, often trying to extract data from old Data Discs and restoring shattered relics. By using this technology, she wants to see if she can bring telesis to society. When she is not working, she usually reads a book under the Wishing Tree in Central Plaza.

Biography Edit

Originally from Ethea, Petra has been traveling all over the known world. For someone so young, she's seen and learned more than most people do in a life time. Petra has only one goal, which is to study relics left over from the past and see if they can bring telesis to society. She eventually came to Portia to study under Merlin and be closer to the Peripheries, hoping to find computer AIs from the past.


Petra was born on Winter of Day 11 in Ethea. Petra had traveled all over the world and learned a significant amount about the Old World technology. Having the goal of studying relics from the Old World, she came to Portia to study under Merlin to be closer to the Peripheries and hoping to find computer AIs from the past. Working in Portia, Petra likes to research old Data Discs to discover forgotten blueprints.

Petra typically disapproves the teachings of the Church, seeing as she wants to use technology to better the world. However, she does agree to destroying dangerous technology after witnessing one of the technology blast a hole on the wall at Vega 5, although she still wants to study it first.

Social talk
If you find anything of value from the old world, please donate it to us. You have no idea how much a discovery can change the world. Don't listen to what the Church has to say, we just want progress towards a better world!
I'm originally from Ethea. I came here because there are several old documents saying there exists a computer artificial intelligence called the All Source around these parts. You still see a robot or two out and about in our cities once in a while, but this All Source AI was supposed to be one of best AIs ever created. I want to meet it!

Social confession
Social propose

Petra is one of many bachelorettes to marry. The player may confess to her upon reaching four full hearts and reaching the "Friend" status. A successful confession changes the relationship status to "Girlfriend" or higher.

Upon marrying Petra, she has a chance to give gifts first thing in the morning.


Petra's unique trait is the ability to extract data from Data Discs. After discovering a Data Disc and taking it to Petra, Petra can examine the data from the Data Disc and provide a new blueprint for the player's workshop. Petra needs a number of Data Disc per blueprint in order to extract new blueprints.

Research NotesEdit

Research NotesResearch Notes

After collecting all the blueprints available from Petra, she will begin trading Research Notes to the player for 10 Data Discs apiece.

As of Alpha 4.0, these Research Notes do not serve any function, as they are currently a work in progress.



Petra typically remains in the Research Center throughout the day. Near evening time, she exits the Research Center to do other activities, such as shopping at Martha's Bakery or reading a book under the tree in Central Plaza.

Some nights she can be seen at the cemetery's entrance, walking around a stone pillar for hours.

Dialogue Edit
