Summary of briefing given prior to running a dungeon:

It's an odd one.  It's fully of delicious food.  There's a grove of bacon trees that marks the portal entrance.  There's a tequila pond.  To reiterate, that is not a typo or autocorrect error.  There's a pond in this dungeon filled with tequila.  The mountain located Dungeon North of the portal is actually composed of what appears to be crystallized sugar.  A wood trellis hosts a vine-based plant bearing candied apples.  This is not an exhaustive list, merely a representative sample.

They did manage to scout it fairly well but don't have consistent down-to-the-minute overlays.  Several of the LIDAR mapping drones flew into clouds that turned out to be composed of marshmellow fluff.  It's a moderately large dungeon, and they know where the boss is. It is, for the record, an enormous open-air saltwater taffy factory with the ability to fling saltwater taffy at range, with enough force to bring down LIDAR scouting mapping.  It may have other capabilities, the DRT squads all avoided it for good reason.  Current theory is that the core's hidden somewhere in the hole in the ground that it draws raw taffy from.

The reason that espers are being called in is because there's an unusual variety of dungeon monsters.  They're ambush predators, and one of the victim retrieval teams was already badly mauled after getting halfway back to the portal.  One of the monsters was described "Like a snake, with wings, that could unhinge its jaw enough to fit my torso in its mouth", while another was described as "A hyena, but pastel-colored, it blends right in with the candy wheatstalks".  The ones that forced the DRT team to undertake a fighting retreat were a sounder of boars with candycane colored tusks and a body that appears to be made out of chocolate.  The specimens are being examined as we speak, but the dungeon isn't worth being held up pending analysis.

In an ideal world, this would have two teams of espers to cover ground more rapidly.  Given that it's a confluence, they're lucky to get the team they have: Aumento, Graviton, and a Korean esper by the codename Raspberry in the west.
