Resonance: A Plague Tale Legacy Relics and Theseus Echoes Guide
Evidence note: launch-dependent details remain marked Retail verification required.
Updated: August 24, 2026
Status: Pre-release information — Retail verification required
Short answer
Resonance: A Plague Tale Legacy includes exploration items connected to the island’s history. Official developer material describes artifacts that reward exploration and draw on real Minoan-inspired objects. Pre-release trophy reporting separately refers to Relics from the present and the past, as well as Theseus Echoes.
The existence of these categories is useful for planning, but their final totals, locations, and tracking systems have not been verified in the retail game. Retail verification required.
What are Relics?
Relics are reported as lore-focused exploration collectibles. The trophy reporting consulted for this guide describes a completion objective for collecting all Relics of the Present and the Past.
Official developer commentary supports the broader idea: artifacts are placed throughout the world to reward exploration and reinforce the setting. It also notes that the objects draw inspiration from Minoan history and imagery.
The final relationship between the in-game terms “artifacts” and “Relics” is not confirmed. Retail verification required for the menu labels, category structure, total count, and completion reward.
What are Present and Past Relics?
The names suggest two historical contexts or collection groups: one associated with Sophia’s medieval-era journey and another connected to the ancient Minoan era. The game’s dual-era structure makes this distinction relevant to exploration, but the exact rules are unconfirmed.
When a location can be viewed in both eras, check it again after a major timeline transition or light-based puzzle. Do not assume that an object visible in one era can be collected in the other.
Retail verification required: confirm whether timeline changes are required for specific Relics, whether the game keeps separate counters, and whether missed items can be recovered later.
What are Theseus Echoes?
The reported trophy list includes an objective to find all Theseus Echoes. Theseus is part of the game’s ancient storyline, so the Echoes may function as narrative or lore discoveries connected to his journey.
That interpretation is provisional. The official material establishes Theseus as an important character and presents the story as a connection between Sophia’s journey and the Minoan past, but it does not publish a complete Echoes list or locations.
Retail verification required for the final name, category, total, chapter placement, story content, and whether Echoes have a separate tracker.
How to track them on a first playthrough
Use a simple three-column note:
Before leaving a major area, check side paths, dead ends, tombs, caves, elevated routes, and newly opened spaces. Revisit an area after a light puzzle changes access if the game allows it.
This is preparation advice rather than a tested route. Retail verification required for map markers, counters, chapter replay, and free-roam cleanup.
Are Relics or Echoes required for the Platinum?
Third-party trophy reporting indicates that collecting the Relics of the Present and the Past and finding all Theseus Echoes are tied to completion objectives. Because the final cross-platform lists and retail behavior are not fully verified, do not yet promise a specific Platinum route or one-playthrough solution.
Retail verification required: confirm PlayStation, Xbox, and PC achievement behavior, exact descriptions, missable status, and whether all progress carries over through replay.
What this page does not confirm
This pre-release overview does not confirm:
- The total number of Present Relics;
- The total number of Past Relics;
- The total number of Theseus Echoes;
- Exact chapter or room locations;
- A complete map or checklist;
- Whether the items are permanently missable;
- Whether chapter select or post-game cleanup exists;
- The exact reward for completing each category.
Every item above is Retail verification required.
Bottom line
Track Relics and Theseus Echoes as separate categories, and check both historical eras whenever exploration opens a new route. Official material confirms the game’s artifact-driven exploration and Minoan setting, while third-party trophy reporting suggests that Relics and Theseus Echoes matter for full completion. A definitive location guide must wait for retail verification.
