This track is the official one made for the reboot version of Toxin Sans (now as Sans).

A single successor to all legacy tracks, such as "Toxinolovania" and "Reincarnation," which are no longer canon. To clarify, those legacy tracks actually never belonged to Underterror (and Toxin Sans) in the first place.

If you happen to read this, well, consider this track is "forgotten", befitting the Underterror's current AU name: "Forgotten World."

"Underterror" is once an Undertale AU that focuses on the old and discontinued fangame, featuring a now-called legacy Toxin Sans.

In the reboot, Underterror was now renamed to "Forgotten World" (also known as "Underterror: Forgotten World), with Toxin Sans becoming a separate and new entity, distinct from its legacy.

Underterror (and Toxin Sans) were currently owned by Meekuzo, as well as legacy and reboot versions.

(Formerly owned by Toxin_)
