📜 V2.5.0 Version Outlook - Part Ⅰ2026-04-16Version Outlook - Part Ⅰ omitted an important detail regarding the "Ethereal Core," causing concern among Keepers. We sincerely apologize! After careful review and discussion, we will make adjustments and provide the following specific explanation:✦ The intended use of the new reward item "Ethereal Core" is: it can be used as "Luminous Core" throughout V2.5.X, and will be converted into a "Pure Core" after V2.5.X ends.✦ All "Ethereal Core" in existing in-game rewards and in the regular event rewards shown in the Version Outlook - Part Ⅰ will be reverted back to "Luminous Core", ensuring that Keepers will not lose any freedom over the rewards

V2.5.0 About Arachne: Perpetual Thrall2026-04-14Who will be buried beneath a foreign sky?Who in the soil of home shall forever lie?Fate hands down its familiar verdict:A white-on-black obituary, nothing more.Prescience illuminates the end,But leaves the grey and murky road unlit.Shall we choose oblivion now,Or devastation at the end?The Master of Fate is its servant too...A prisoner bound within her self-made web.No time to weep, no time to laugh—Still her hands turn the spindle, never to rest."Within this cage of fate, we come with naught—and naught is all we share."
V2.5.0 New Awakener✦Arachne2026-04-13"Is it tragic? Is it despairing? This web with no end... always on the verge of completion, always coming undone.""To keep the Wheel of Fate turning true, moment unto moment, age unto age... such is the eternal duty of the Weaver." ✦ Arachne CV: Ōnishi Saori
