Virtue Rewarded? by Arcadia
Five thematic entries (I to the eponymous V, who must be identified at the foot of the grid) are unclued. Across clues are in alphabetical order of their answers, all bar one requiring thematic transformation before entry. Information in brackets refers first to final grid entries; then to clue answers. Down clues and answers are normal. Clashes occur in four symmetrically placed cells, in which solvers should enter both clashing letters. Arranging them appropriately could loosely enable II to __ __ (4,4) I, while III __ __ (4,4), as tasked by V, despite the attentions of IV. All thematically adjusted entries are unique and in Chambers, though heaven knows why.
