I guess I missed the timing of the discussion but anyway: Dimaria's epithet isn'treference to her magic. From what I understood, she's the War Maiden/Valkyrie because she's come victorious in any battle she got involved so people (not herself) started calling her that. Maybe she never used her Chrnos form in any battle because her power of stopping time is just that OP.
