Integration— Bloodlines are divided into many forms of integration with the source. The more integrated a lineage is, the greater the comprehension ability of the bloodline.

Example: Compared to a normal Goblin Bloodline and an equally common Fiend Bloodline, due to the higher integration of the Fiend bloodline to the source, the skills and innate knowledge known to the Fiend would be greater.

Evolution Codex: It is a mystical item categorised into conceptual items that can allow the hosts to trigger their evolution charts if the rank is appropriate to the codex. It is in shape of a grimoire.

Evolution Atlas: Each living being has its own, unique evolution atlas that holds the secret of evolution unique to the lifeform.

Evolution: Each evolution process is divided into two parts— Spiritual and Physical. While the Spiritual Evolution is completed in an instant, the process of the Physical Evolution would finish after an appropriate level of nutrition is reached.

Neutral Gene: With Each evolution, a neutral gene within an organism is created that would slowly get imprinted with the spirit after the Spirit Evolution before that very neutral gene gains the necessary information to commence the physical evolution.

In simple terms, spiritual evolution dictates the 'direction'of the evolution which is imprinted on the Neutral gene. Then, the neutral gene will drive the body appropriately to achieve the anticipated physical evolution.

Evolution Trigger: To trigger evolution, the host must collect blood of higher evolved organisms or astounding amount of the blood of the equally tier living beings.

Effects: In extreme cases, the evolution would lead to drastic physical changes. But oftentimes, evolution may unlock hidden stats or better, exotic skills within the hosts. Many affiliations also have a special treatment for the highly evolved hosts.
