Well I am glad you are thinking it thoroughly! Other feedback I would have are minor, just things to think about until mortals start popping up in the setting: To the minds behind strategic planning, she is their muse."

Strategy/tactics/intelligence are typically governed by Wisdom, Knowledge, or Strategy deities distinct from battlefield-combat war gods. Athena vs. Ares, essentially. If another player makes a god of Wisdom/Strategy, there's bound to be overlap. Not that it's a bad thing, however it helps both players and me as the GM to have a general idea of where one Domain ends and another one starts. 

Does Adria govern Combat tactics (battlefield decisions), Grand strategy (campaign planning, logistics, politics), or both? The same applies for the whole "appears in front of dying soldiers, soothing them as they take their last breath" kind of thing. 

Do you want your deity to take a quasi-ferryman of souls in place of a proper Death Domain god, until a player comes with us with a concept of one? How far do you expect to take this facet of Adria?
