According to multiple recent Genshin Impact 6.3 leaks, Luna IV is shaping up to be a heavily character focused update. While everything remains unconfirmed until HoYoverse publishes an official preview, several reliable leaker circles broadly agree on a three character structure. These are the long awaited Columbina, the enigmatic White Horse Adeptus, and a still unknown Liyue 4 star character that is expected to arrive with the Lantern Rite cycle.
Current reports describe Columbina as a 5 star Hydro Catalyst user whose banner is planned for the first phase of Version 6.3. Multiple summaries of leak compilations and banner roadmaps list her as the headline character of Luna IV, emphasizing her status as a Fatui Harbinger and tying her debut to the ongoing Nod Krai and Luna storylines.
Gameplay descriptions vary, but most agree she will function as a powerful off field Hydro applicator with strong reaction enabling potential, which matches community expectations for a premium Hydro unit that can fit into many existing team cores.
The second major name is the White Horse Adeptus, frequently described as a 5 star character associated with Liyue and thematically linked to legends around celestial or lunar imagery. Early translations call her the “Celadon Mare” or a daughter of an ancient being such as Istaroth or Astaroth, and leaks consistently stress that she is not an Anemo unit, even though the Adeptus theme might initially suggest that element.
Elemental typing for White Horse Adeptus is still under debate, with some sources suggesting Geo or Dendro due to her connection to Liyue and nature motifs. Until the closed beta reveals her kit, her role remains speculative, but expectations are high that she will pair well with existing Liyue characters and play a key part in the Lantern Rite narrative.
Alongside these two 5 stars, leak roundups also mention an unnamed 4 star Liyue girl slated to appear as a new addition to the standard event banner lineup for 6.3.
Details about her element, weapon, and role are minimal. Most sources only agree that she is tied to Liyue’s civilian side rather than the Adepti, possibly representing a performer, artisan, or organizer connected to the Lantern Rite festivities. This character is expected to be featured on at least one of the limited banners, making her relatively accessible for players who pull for Columbina or White Horse Adeptus.
It is important to note that 6.3 also appears closely linked to a large map expansion and a major story beat, which supports the idea that these three characters are thematically central to the update. Recent reports claim that Luna IV will introduce a new region roughly half the size of Natlan, larger than Nod Krai’s current explorable area, providing fresh context for Columbina’s arrival and additional lore hooks for the White Horse Adeptus and the new Liyue 4 star.
This combination of new story, exploration, and high profile banners explains why the leak community is treating 6.3 as a cornerstone patch in the late Luna cycle roadmap.
As always with Genshin Impact leaks, all information about Columbina Hydro Catalyst, White Horse Adeptus, and the unknown Liyue 4 star must be treated as provisional until HoYoverse reveals official splash art and character demos. However, the consistency across multiple leak sources makes it increasingly likely that these three units will define the playable roster for Genshin Impact Version 6.3 Luna IV and will strongly influence future team building, Hydro reaction compositions, and Liyue focused meta strategies.
