This is a Warhammer 40000 52-16 Adepta Sororitas: Dialogus 2021 plastic kit

The kit builds a single Dialogus, who bears a variety of microphones and vox-speakers with which to amplify her holy oratory across the battlefield. A lectern hovers in front of the Dialogus, with relic parchment hanging down from it and additional verses on the candle-topped rostrum.

This set is supplied in 10 plastic components and contains a Citadel 40mm Round Base.
