Project Solaris Characters & Relationships
Know who you are raising, commanding, and visiting across the 100-day climb.
Project Solaris follows Solaris, a failed mage who wants to become full-fledged and travel beyond the Island, alongside Hom (also called Homu), the partner she commands in battle through Quick Time Events. Around them stand classmates, family, shopkeepers, mentors, and at least one figure best left lightly spoiled until you meet them in a run.
This Characters Hub orients you before deep pages. It explains how cast investment competes with battle and craft days, then links to focused write-ups. Greenhorn’s single-player roguelite deckbuilder JRPG makes relationships mechanical: Trust changes which skills Hom can land, and card choices open sub-scenarios that alter endings.
Why characters matter to builds
You are not collecting a twelve-person combat roster. You are allocating scarce days among combat, social, shopkeeping, development, and rest. Visiting Tetia or listening to Melchior is not only flavor—it can unlock story routes while still feeding the Reliability that makes hard QTEs realistic. Ignoring people can leave you with a strong deck and a hollow ending, or with missing context for why a Trial feels personal.
Use character pages together with Beginner builds and the day planner so social days are scheduled instead of accidental.
Roster map
- Solaris — protagonist goals, alchemy weapons, and how player decisions express her ambition.
- Hom — combat agent, Trust loop, and equipment synergy.
- Supporting cast — Tetia, Croisé, August, Melchior, and spoiler-light notes on the mystery figure.
For systems that sit under these faces, browse Builds, Guides, and Updates after launch patches change balance or story tooling.
Trust, days, and endings
Trust is the bridge between character writing and combat meta. Raising it makes difficult skills easier to activate—exactly the fantasy of partners learning to communicate. That means Hom’s page is required reading even if you only care about Trial clears.
Multiple endings respond to how you spend the hundred days and which sub-stories you complete. A launch-window tip: pick one relationship priority per run besides Hom, rather than sprinkling single visits everywhere. Depth beats checklist tourism when calendars are tight.
Combat fantasy versus social fantasy
Solaris wields alchemy weapons that cost resources for big swings. Hom wears craftable gear with passives and executes the skill deck. Understanding that split prevents frustration when a “character build” actually means three systems—see Equipment rankings and Skill rankings.
If you are brand new, start with Getting Started, then return here to decide who you will invest in during block one.
Spoiler policy on this wiki
Character articles stay light on late revelations. The supporting cast page names roles and relationship tips without walking through twist-by-twist plots. When community patch notes or Steam news add cast content, check Launch notes rather than inventing details.
How to use this hub during a run
Before each Trial block, ask: whose scene am I advancing, is Hom’s Trust high enough for my deck, and does August-related money time need a slot? Write the answers into your day planner. After the ceremony, update relationship priorities the same way you update skills.

Frequently Asked Questions
Quick answers for Project Solaris players.
Who are the main playable focuses?
You guide Solaris through the calendar while Hom executes combat via QTEs. Builds revolve around their Trust, skills, and gear rather than a large interchangeable roster.
Should I talk to everyone every day?
No. Days are scarce. Pick Hom plus one relationship priority per run, and schedule social cards deliberately around Trial prep.
Do characters change my ending?
Sub-scenarios and how you spend the hundred days influence multiple endings. Cast investment is part of route control, not only flavor text.
Where do I learn combat roles?
Read Hom for Trust and execution, Solaris for alchemy weapons, then Skills and Equipment under Builds for ranking details.
