This is a Warhammer Age of Sigmar 92-12 Sylvaneth: Alarielle The Everqueen plastic kit

This multi-part plastic kit contains all the components needed to assemble Alarielle the Everqueen, riding her gigantic wardroth beetle – a living battering ram covered in moss, fungi and decorated with soul amphorae and other trinkets. She wields the Spear of Kurnoth in one hand, and her other arm ends in the dreaded Talon of Dwindling. 79 components in total, with an appropriately huge Citadel 160mm Round base.
