  Five-dimensional braneworld constructions in anti-de Sitter space naturally
lead to dark sector scenarios in which parts of the dark sector vanish at high
4d momentum or temperature. In the language of modified gravity, such feature
implies a new mechanism for hiding light scalars, as well as the possibility of
UV-completing chameleon-like effective theories. In the language of dark matter
phenomenology, the high-energy behaviour of the mediator sector changes dark
matter observational complementarity. A multitude of signatures---including
exotic ones---are present from laboratory to cosmologic scales, including
long-range forces with non-integer behaviour, periodic signals at colliders,
`soft bombs' events well-known from conformal theories, as well as a dark phase
transition and a typically small amount of dark radiation.
