Hiwfite

Hiwfite is one of the Pencilcosmos' most corruptive substances. Hiwfite is able to corrupt practically anything, with a few exceptions.

Formation
The first Hiwfite was first seen in a ring-like formation around The Hole after the Pencils escaped The Black Realm when The Hole was consuming The Black Realm. A few texts have described this event, although with little details or any real or plausible explanation. This ring of Hiwfite soon disappeared, and to this day, The Hole has never consumed The Black Realm.

Properties and Usage
Hiwfite is incredibly corruptive and very dangerous. Hiwfite is able to kill Multiversal level gods if exposed to long enough, and simply looking at Hiwfite is enough to kill an average creature. Because of Hiwfite's extremely dangerous properties, it has been used in war countless times, although Hiwfite weapons have mostly been banned across the Omniverse due to The Hugghiguyughiyuguhi Wars of 1032 LPT. Because of this, Hiwfite weapons fell out of use after the war, although they continue to be used in areas and verses beyond the Omniverse.

Ways to Stop Hiwfite
A few substances, both natural and artificial, have been created to resist Hiwfite and its properties, such as Swekn, the material that makes up the Stableverse's border.
