Research Projects
Demetrius is involved in several research projects throughout the game, some of which directly impact gameplay.
Cave Survey
Early in the game, Demetrius sends the player a letter asking them to complete a cave survey. This involves taking items from the mine and bringing them to him. Completing this survey helps Demetrius with his research and can trigger additional events.
Agricultural Research
Demetrius is always studying crop growth, soil conditions, and farming techniques. His research sometimes leads to new discoveries that benefit the player, such as information about optimal growing conditions.
Special Order Research
In some cases, Demetrius may offer special orders related to his research. These quests typically involve collecting specific items or data from the environment.
Family Dynamics
Relationship with Robin
Demetrius and Robin have a loving but sometimes strained relationship. Robin is patient and supportive of Demetrius’s work, but she sometimes wishes he would spend more time with the family. Their dynamic is one of mutual respect, with Robin providing the emotional warmth that balances Demetrius’s analytical nature.
Relationship with Maru
Maru is Demetrius’s biological daughter, and they share a close bond through their mutual interest in science and learning. Demetrius is proud of Maru’s intelligence and encourages her pursuits, though he sometimes forgets to show his appreciation in ways that are meaningful to her.
Relationship with Sebastian
Sebastian is Robin’s son from a previous relationship, and his relationship with Demetrius is more complicated. While there is no open hostility, there is a noticeable distance between them. Sebastian sometimes feels overshadowed by Maru’s close relationship with Demetrius, and Demetrius sometimes struggles to connect with Sebastian’s different interests and personality.
