What is Tracing the Trail?
Tracing the Trail is the longest bar on the calendar. It opens on 20 September 2026, four days after launch, and runs to 9 December 2026, which is six weeks past the end of the rest of the launch season.
The official calendar lists only the dates. The closed beta version of the calendar, printed inside the Welcome to Idyll notice, ran it under a longer name, Tracing the Trail: The Shadow of Legend, but neither version carries a published description.
Only two events on the whole calendar reach 9 December 2026: this one and Legendary Journey: Walking with Irisalis & Gift of Blessing. They open five days apart and close on the same day.
Dates and windows
| Window | Dates | Days | Featured Aniimo | Status |

 Window 1 | 20 September 2026 to 9 December 2026 | 81 | TBD | Starts in 5 days |
Dates are the UTC+8 calendar days the official calendar publishes. The source gives no time of day, so treat the last date as the whole of that day in UTC+8 and do not leave a reward to the last hour of your own.

Tips
Almost twelve weeks is long enough that there is no rush in September, but it is also long enough to forget: 9 December 2026 is the deadline.
It shares its closing date with the Irisalis Legendary Journey, so if the two are connected, finishing the Legendary Journey first is the safer order.
It opens on 20 September, not on launch day, so there is nothing to look for on 16 to 19 September.

Tracing the Trail FAQ
When does Tracing the Trail start and end?
From 20 September to 9 December 2026, in UTC+8 calendar days, per the official event calendar.
Is Tracing the Trail still available?
It runs for almost twelve weeks and closes on 9 December 2026, later than every other event on the launch calendar except the Irisalis Legendary Journey.
What do you do in Tracing the Trail?
The official calendar lists only the dates; the tasks are not published yet.
What are the rewards?
Rewards for Tracing the Trail are not published yet. Neither the launch calendar nor the closed beta calendar attaches a reward list to it.
Is it the same as the beta’s Tracing the Trail: The Shadow of Legend?
The beta calendar used that longer name. The launch calendar drops the subtitle and publishes no description, so we cannot say whether the content is the same.
Why does it run past the rest of the calendar?
The published calendar grid only covers 16 September to 28 October 2026, but two bars carry dates beyond it. Tracing the Trail is labelled 9.20 to 12.9, which is 20 September to 9 December 2026.
Every date on this page is the UTC+8 calendar day the official source publishes, re-checked on 14 September 2026. Rewards the game has not announced are written as such rather than estimated.
