After Heartseeker falls at Still Shore, a letter attributed to someone surnamed Chu reads like an oath of hatred. The localization over-reads 恨 as animosity; the line quotes Jiang Yan's *Henfu* — sorrow at irreparable loss.
[spoiler]Thirteen years before the present, Emperor Chai Rong's Hidden Swallow sent face-changed patriots north after the Yanyun cession. Chu Qingquan volunteered; Han Xiangxun refused to alter her lover's face. She severed ties with the Hanging Blade until urgency returned three years ago: Tian Ying stole her surgical scroll and tools during a Palace of Annals banquet laced with sleeping drafts. Chu was ordered to hold her at Peace Bell Tower; the bell shattered and Han swore never to see him again.
The broken mirror shard etched with 楚 is the sundered half of a lovers' reunion proverb. Yi Dao arrives not as Han's enemy but an old friend; together you uncover Aureate Pavilion tunnels beneath Blissful Retreat — dream-puppet cocoons proving Li Zuo inherited Sun Buqi's immortality experiments.
Yi Dao reports Chu Qingquan perished at Blackwater City. Han pours parting-tears wine for a man she swore off yet never released, then orders Heaven's Pier abandoned. Still Shore's Chinese name 弱岸 (feeble-water shore) and Han's Water Lady code tie the dungeon to unbridgeable distance between lovers and the faceless who can never return.[/spoiler]
