  We explore the cosmological dynamics of a minimalistic yet generic
string-inspired model for multifield dark energy. Adopting a supergravity
four-dimensional viewpoint, we motivate the model's structure arising from
superstring compactifications involving a chiral superfield and a pure $U(1)$
gauge sector. The chiral sector gives rise to a pair of scalar fields, such as
the axio-dilaton, which are kinetically coupled. However, the scalar potential
depends on only one of them, further entwined with the vector field through the
gauge kinetic function. The model has two anisotropic attractor solutions that,
despite a steep potential and thanks to multifield dynamics, could explain the
current accelerated expansion of the Universe while satisfying observational
constraints on the late-times cosmological anisotropy. Nevertheless, justifying
the parameter space allowing for slow roll dynamics together with the correct
cosmological parameters, would be challenging within the landscape of string
theory. Intriguingly, we find that the vector field, particularly at one of the
studied fixed points, plays a crucial role in enabling geodesic trajectories in
the scalar field space while realizing slow-roll dynamics with a steep
potential. This observation opens a new avenue for exploring multifield dark
energy models within the superstring landscape.
