Project Solaris Supporting Cast

Project Solaris surrounds Solaris and Hom with people who make the Island feel inhabited: a brilliant former classmate, a strict-but-kind mother, a lazy shopkeeper, a wise mentor figure, and at least one presence best discovered in play. Side scenarios appear when you select certain cards or hit objectives, and endings shift based on how those threads resolve.

This page stays spoiler-light. It explains roles, relationship tips, and how to schedule cast time beside Trials. For the leads, read Solaris and Hom. For calendar math, use the day planner and 100-day strategy.

How side stories compete with meta

Every social visit is a day not spent crafting Hom bulk, buying a Solaris alchemy weapon, or grinding a skill. That is not an argument against cast investment—it is an argument for intentional investment. Launch-friendly approach:

1. Keep Hom’s Trust above the floor your deck needs.
2. Choose one supporting cast priority per run.
3. Schedule two to four focused touches per twenty-day block rather than random one-offs.
4. Protect Trial week from brand-new relationship experiments.
5. On a second run, swap the priority to see another ending facet.

Tetia — former classmate, sharp and young

Tetia is described as a young but brilliant former classmate. Relationship tip: treat her thread as peer pressure and peer insight. She is useful when you want a run that measures Solaris against someone who already looks “ahead” on the mage path.

Scheduling tip. Early-block visits help establish the thread before mid-game calendars get craft-heavy. If you are on a Skill Spam archetype, pencil Tetia on days you were tempted to over-Develop anyway—swap one Development card for her scene so combat obsession does not erase classmate continuity.

Build crossover. Tetia runs pair well with Balanced Trust because you are already budgeting social days. See Beginner builds.

Croisé — strict but kind mother

Croisé (sometimes styled Croise in English materials) frames home pressure and care. Relationship tip: her scenes often read as accountability. If your Solaris fantasy is “prove I belong,” Croisé’s thread sharpens that theme.

Scheduling tip. Do not park every rest day as empty space—occasionally convert recovery into family-facing social picks when the card offer allows, especially after a failed fight week when the story of care matters.

Build crossover. Players who tilt too hard into money rush can use Croisé touches as a reminder that the Island’s expectations are not only unpaid bills. Keep Hom’s Trust intact while you visit; family scenes do not replace partner training.

August — lazy shopkeeper

August is the shopkeeper energy in the cast list. Even players who skip banter feel his system shadow through shopkeeping cards and money flow.

Scheduling tip. If your archetype is Money Rush, August-related days are not optional flavor—they are the engine that funds Solaris alchemy milestones and Hom craft batches. Read Equipment rankings before you dump a block into shopping with no wishlist.

Relationship tip. Laziness in the text is a tone cue; mechanically, you still need discipline. Use shopkeeping when prices and Trial distance make sense, not as doomscrolling between panics.

Melchior — wise expectations

Melchior is a wise woman with high expectations for Solaris and Hom. Relationship tip: her thread suits players who want mentorship pressure—someone who believes the pair can clear the path if they communicate.

Scheduling tip. Melchior visits pair naturally with Trust-focused planning. After a Trust spike that unlocks harder skills, a mentor scene can narratively “certify” the growth you just earned in combat practice.

Build crossover. Skill Spam players should still reserve Melchior slots if they want that ending flavor; pure damage calendars starve mentor routes.

Mystery figure — spoiler-light only

Official marketing and community chatter point to deeper antagonism and secrets beneath the cute pixel surface. This wiki will not diagram the twist tree. Practical tip only: when a run presents an odd card, an unexpected encounter, or a flag that feels out of place beside the everyday Island cast, do not auto-skip it on a story-focused attempt. On a pure combat attempt, note it for the next save file.

If Steam news or patches add cast content after September 20, 2026, check Launch updates instead of trusting outdated rumor sheets.

Per-block cast template

Block goal line. “Hom Trust floor + Tetia depth” (example). Days 1–7. One cast touch + combat learning. Days 8–14. Money or Development per archetype; optional second cast touch if cards allow. Days 15–20. Trial prep; no new route gambling unless the scene is already mid-thread and short.

Write the goal line at the top of your day planner.

Endings without spoiler maps

Multiple endings respond to how you weave the hundred days. You do not need a datamined flowchart on day one. You need repeatable habits: finish what you start with one cast member, keep Hom capable, and accept that another ending waits on the next run. That is healthy roguelite-JRPG design, not incompleteness.
