  We construct a multiverse model based on a recent proposal for dS wedge
holography, where empty AdS$_3$ space is cut off by a pair of accelerated
dS$_2$ space universes, one near the AdS boundary, denoted the UV brane, and
one in the AdS interior, the IR brane. We glue together several copies of this
configuration along the UV and IR branes in a periodic matter. To provide the
model with dynamics of the like near Nariai black holes used in other
multiverse toy models, we add dS JT gravity as an intrinsic gravity theory on
the IR branes. We then study the entanglement entropy with respect to a UV
brane observer, who finds a Page curve transition due to an entanglement island
connecting the UV and IR branes. This process involves the coarse-graining of
information outside the causally accessible region to the observer. Our model
provides an explicit realization of entanglement between IR and UV degrees of
freedom encoded in the multiverse.
