The Lunar event in Creatures of Sonaria appears to be tied to the Disaster Event , and the latest public source I found says that the 2026 Disaster Event released on May 22, 2026 with a “Return of the Lunar” note.

Quick Scoop

  • The clearest current signal is that the Lunar-related content showed up with the Disaster Event on May 22, 2026.
  • A separate event post from 2025 also shows the same event type ran in mid-to-late May , specifically May 16 to May 30, 2025 , which suggests the Lunar event is usually part of that May event window rather than a fixed year-round feature.
  • So, if you’re asking when it happens, the best answer right now is: around late May, during the Disaster Event.

What this means

  • If you missed it this year, it likely was a limited-time event rather than something always available.
  • The wording from the 2026 event source suggests the Lunar content was a returning feature inside the broader disaster-themed event.
  • Fan coverage also points to the event being active “now” around that period, which lines up with the late-May timing.

Best estimate

  • Expected timing: late May.
  • Observed 2026 start: May 22, 2026.
  • Observed 2025 window: May 16–30, 2025.

TL;DR: The Lunar event in Creatures of Sonaria seems to return during the Disaster Event, and the latest available info puts it in late May , with May 22, 2026 being the most recent start date I found.
