Noiran’s Hidden Legacy

Noiran’s Hidden Legacy is a Transcendence dungeon announced for the Korean service on 17 June 2026, in the run-up to the Chapter 1 update. NCSOFT’s wording pairs it with an existing dungeon: "The Transcendence dungeons, Noiran’s Hidden Legacy and Abyssal Horn Den, as well as the Sanctuary dungeon, Snowfield of Sorrow, will also be updated." Note the verb — updated, not released — and that the delivery announcement of 6 July 2026 names Abyssal Horn Den and not this one. It has not been announced for the Western release.

This dungeon enters the official record on 17 June 2026 (official NCSOFT announcement, same date), in a sentence announcing that three dungeons "will also be updated" as part of Chapter 1. When that update shipped on 6 July 2026, NCSOFT’s announcement described Abyssal Horn Den in detail — a Transcendence dungeon requiring level 50 and a minimum item level of 3,500 — and did not mention Noiran’s Hidden Legacy. This site records what was announced and marks clearly that delivery under this name is not confirmed by a later dated source.

The published record gives a name, a type and one announcement date, and stops there. It is worth being explicit about a temptation this page refuses: the Transcendence dungeon announced beside it, Abyssal Horn Den, has a published entry requirement of level 50 and item level 3,500 — and it would be easy to assume the same applies here. NCSOFT did not say so. What does apply to Transcendence dungeons in general, from the announcement of 6 July 2026: five-player parties, and entry tickets replaced by Odyle Energy on the reward side.

Before anything else: this dungeon is not confirmed for the Western release, and its delivery on the Korean service is not confirmed either — only its announcement is. The mistake to avoid is the one this page is built to prevent: assuming that content announced in the same sentence as another shares its numbers. Abyssal Horn Den has a published entry requirement; this one does not, and inventing one would be exactly what the rest of this site exists to avoid. If you find an entry item level for Noiran’s Hidden Legacy elsewhere, it did not come from the publisher.
