Thinverse

A Thinverse is a verse which has a thinner barrier than most other verses.

Thinverses are formed when a verse collides with a large object and is rubbed against that object extremely hard, breaking off a huge portion of the verse's barrier which turns it into a Thinverse.

Thinverses are very vulnerable to attacks, even more so than an Anchorverse, so most civilizations who start out in a Thinverse eventually migrate out to find a less vulnerable verse to live in.

The exact definition of a Thinverse is quite arbitrary, although most creatures agree that a verse with at least 70% of its barrier being 10 meters or thinner is a Thinverse. Verses with no barriers at all do not count as a Thinverse.

A few Thinverses have a barrier so thin it is practically see-through. Most of these special Thinverses, known as Superthinverses, have been studied extensively.

There are approximately  Thinverses.
