Jake Thayne

Jake Thayne is the main protagonist of The Primal Hunter. Following Earth's integration into the multiverse and the System, Jake quickly distinguished himself as an outlier among humanity due to his rare bloodline and exceptional combat potential. Gifted with the Bloodline of the Primal Hunter, he begins his journey with an innate affinity for hunting, survival, and ranged combat, particularly archery, a skill in which he already excelled prior to the System's arrival.

Questions

What is System Codex?

System Codex is a spoiler-aware reading companion for LitRPG and progression fantasy. It helps readers check character sheets, skills, items, titles, and progression without accidentally running into spoilers.

How does spoiler protection work?

Readers can set their position in a series, and System Codex will show information based on where they are. The goal is to let you refresh yourself on what has already happened without seeing details from later books or chapters.

Is System Codex official?

Some codexes may be official or author-managed. Unless clearly marked as official or author-managed, a codex should be treated as unofficial, community-created, or proof-of-concept.

Can authors claim their series?

Yes. Verified authors can claim their own series for free, with basic tools for correction requests, representation concerns, image preferences, and review of unofficial codexes relating to their work.

How does System Codex use AI and artwork?

System Codex may use AI for limited presentation features, such as AI-generated visual aids or short system-style lines, but codex information is manually created, curated, or reviewed by people. Human-made artwork is prioritised and can be credited. Read the full AI & art policy for more.
