  In this paper, we propose a model based on wedge holography that can describe
the multiverse. In wedge holography, we consider two gravitating baths, one of
which has strong gravity and the other one has weak gravity. To describe a
multiverse, we consider $2n$ Karch-Randall branes, and we propose that various
$d$-dimensional universes are localized on these branes. These branes are
embedded in $(d+1)$-dimensional spacetime. The model is useful in obtaining the
Page curve of black holes with multiple horizons and in the resolution of the
``grandfather paradox''. We explicitly obtain the Page curves of eternal AdS
black holes for $n=2$ multiverse and Schwarzschild de-Sitter black hole with
two horizons.
