Servant of Darkness

Servant of Darkness (異界のしもべ, Ikai no Shimo Be, lit. "Servant of the Otherworld") is one of the first three Empress' Research maps, alongside Arcane Confluence and Demon's Park. It has four stages and disappears for the rest of the day after clearing one, so it will take at least 4 days to clear the whole map. Once completed, the Wicked Tank event will be unlocked.
