Dr. Killian spent his life mentoring unstable minds, until one of his patients killed him.

His next life begins in a fantasy world he vaguely recognizes from the same patient’s ramblings about a novel Killian never bothered to pay attention to.

Reborn as Atheline Sunblade, a high elf noble from a family second only to the throne, Killian discovers his original role in the story was insignificant: he was simply the man sent to capture the villainess runaway fiancée.

Determined to avoid the plot entirely, Killian plans to live quietly.

Unfortunately, fate seems to have a twisted sense of humour. 

Instead, he casually befriends what he assumes is a normal dark elf soldier visiting the elven kingdom. 

She’s intense, strangely curious about him, and appears far too often for his liking , but Killian doesn’t think much of it after all every Dark elf he heard of was  pushy to begin with.

Until a cultural misunderstanding and several extremely unfortunate assumptions lead to one catastrophic realization.

The “soldier” he’s been talking to… is actually the Dark Elf Queen.

And somehow, he accidentally proposes.

To make matters even more fucked up, he got a system that basically gives him useless things.

.....
It will have smut scenes and I will mark them for those who don't want to read them.

AUTHORS NOTE.
It's wise that you read it, you might get transmigrated into the book one day if you ignore it.

All individuals capable of manipulating aether are classified by rank:


E → D → C → B → A → S → SS → SSS → EX → Mystic → Sovereign


Note: The ranking system may evolve as new forms of power are discovered.


At the center of the world exists the World Tree, the source of all aether.


• The World Tree releases raw aether into the atmosphere


• This raw aether is naturally refined by environmental forces


• Different celestial and natural influences shape it into distinct types


• Living beings absorb the type of aether they are most compatible with, which they then convert into their element.


Each aether type is tied to a natural or celestial source and is typically aligned with specific races.


• Source: Plant life (similar to photosynthesis)


Instead of absorbing refined aether, Beastkin take in raw aether and convert it within their bodies into personal power


NOTE:The converted Aether absorb will be turned into your element in the core, except for the beast kin who dominate in strength, but there are unique ones that wield Elements.


●Excessive absorption of aether has extremely bad effects. The world runs on the concept of not being greedy. Those who absorb too much for their core except when advancing have a greater chance of getting corrupted.  Basically like a magical zombie.


4. Body Strengtheners (Non-Elemental Path)


Not all warriors manipulate external aether types.


Body Strengtheners possess an Aether Core but do not align with any element. Instead, they channel aether directly into their bodies and weapons.


• Enhanced strength, speed, and durability


• Practitioner → Veteran (1–3 Years)


Unlike elemental users, their growth depends heavily on discipline, training, and physical limits rather than affinity.


I'll add the world next after I manage to create a coherent world map
