This instance was called Skull Dungeon. It sounded like a gathering place for undead monsters, but that was not actually the case.
The monsters entrenched here had long since been thoroughly studied by exploration-loving sorcerers. They were groups upon groups of Beauty Pythons!
In the Prime Material Plane or elsewhere in the multiverse, encountering so many Beauty Pythons was extremely difficult. For one, this species was already on the verge of extinction. Sometimes, only mutated Beauty Pythons could be found in hellholes like the Astral Realm, but they were vastly different from the original pure bloodline. For another, Beauty Pythons were not social creatures to begin with. Once most of them reached adulthood, they developed an extremely strong sense of territory. Dying of old age without ever interacting with one another was the norm.
As everyone knew, in Pro World, Beauty Pythons possessed a charm rating even more terrifying than succubi. Long, long ago, tales circulated across the continent of adventurers stumbling into Beauty Python dens and ultimately becoming smiling skeletons. That alone was enough to prove how frightening they were.
The name Skull Dungeon had come from this.

Since it was an instance, sorcerers exploring this place would not truly die. Because of its unique nature, Skull Dungeon had instead become one of the five most famous instances in Lost Paradise.
Many amorous mid-level sorcerers even ran into Skull Dungeon whenever they had nothing better to do, supposedly to use the Beauty Pythons' overwhelming traits to temper their willpower resistance. God knew how those who were instantly defeated by beauty inside were supposed to train their willpower. In
