Jim is very right about how the rules were meant :)On the other hand, you see only final result - some compromise between theme and complexity/fiddlyness. There were another "thematic rules" that were dropped during development. For example blocking and shooting was more difficult at night originally (so the night combats were bloodier - it was more often to take damage and then kill the opponent), but I dropped that for various reasons. I admit dungeons and tombs are kind of relics from these times... but I liked the option to cast black spells during day and there may be units or enemies that work different way at day and night in the future etc., so I kept it.
