I also made another separate super-series called "Numbers of the Prolific East", which is themed from the Eastern world, primarily in East and Southeast Asia. Songkran numbers also belong to this series as well. This super-series is also significantly smaller than Numbers of the Feracity and should not be converged with the latter one.
[1] Nam Dang Nam Som — Reference to the popular Thai hip-hop song "Nam Dang Nam Som" by Jarvis with over 110 million views on YouTube. Initially planned with 5 numbers. Currently inactive.
[2] APT. Killer Kingdom (final) — The 13 numbers named after the "hyper-irony" hit "APT." by Rosé and Bruno Mars.
Holiday Special:
Songkran numbers (holiday number) — Used to celebrate Songkran days on April 13–16.
