Hidden Marriage Candidate

Caldarus: Unlocking the Dragon

Mistria's dragon guardian is the game's hidden marriage candidate. Here's exactly how to unlock his human form, how his friendship actually levels, and what he loves.

Caldarus, the dragon guardian of Mistria

Caldarus

Dragon Guardian · Birthday: Spring 25 · Hidden Candidate

Caldarus is bonded to you when you repair his broken statue early in the story. He appears in your dreams before Spring 3 asking for Essence, and repays you with skill upgrades as you descend the mines. Centuries of being sealed away left him with amnesia — and no idea how humans work.

First impression: formal and distant — he calls you "mortal". Old soul, lonely heart.

How to Unlock His Human Form

Caldarus can't be romanced as a statue (or a dragon). Three things stand between you and his human form:

  • Reach floor 60 of the mines — the mines guide covers the fastest way down.
  • Break the Fire Seal (story quest "Breaking the Fire Seal").
  • Complete the ritual at his shrine.

How His Friendship Actually Works

Caldarus has no traditional heart events. His hearts unlock through the main mines questline instead:

HeartsUnlocked By
2Story quest "The Water Tablet"
4Story quest "The Earth Tablet"
6Story quest "Breaking the Fire Seal" — after this he sends you a Marigold every birthday
8"Life in This Form": dinner at his Deep Woods temple — onion soup (he forgot to dice the onions), mushroom rice (far too much soy sauce), and a confession. You choose Best Friends or the romantic route.
10Not yet implemented in-game — the official wiki lists it as "To Be Released".

Caldarus's Loved Gifts

He's learning human customs from scratch, and food is his favorite lesson — all cooked dishes land well, and these land best:

  • Apple Honey Curry, Fried Rice, Harvest Plate, Mont Blanc
  • Seafood Boil, Seafood Snow Pea Noodles, Spring Galette, Sushi Platter, Veggie Sub Sandwich
  • Statuette of Caldarus — yes, he loves tiny statues of himself

⚠️ Light Spoilers Above

The quest names alone hint at mid-game story beats. If you'd rather go in blind, just remember: keep descending the mines and follow the story. The romance guide has the spoiler-lighter overview of all candidates.
