Abstract: Using $textit{Gaia}$ DR3 astrometry and spectroscopy, we study two new substructures in the orbit-metallicity space of the inner Milky Way: $textit{Shakti}$ and $textit{Shiva}$. They were identified as two confined, high-contrast overdensities in the $(L_z, E)$ distribution of bright ($GarXiv:2403.13051v1 Announce Type: new
