An extremely dangerous high magic world.
It might even be a cesspool, unsure whether it's a small one or a super large one.
Duncan observed the dimensional marker, which was very unstable, with space itself in chaos. This meant the anchor points might not belong to the main material plane. The world Duncan anchored was somewhat similar to the right mouth for fishing; locking onto the main material plane is the right mouth. Generally speaking, the main material plane is the safest place, allowing time for the human form to develop.
As for the non-right mouth space anchor points, nobody knows where they might lead.
Perhaps directly anchored to the monster's home.
This exploration Duncan undertook was in a broad net casting mode, expanding the opportunity to find other worlds by consuming legends, so the space anchor points had high randomness.
Buzz!
