Sacred Haven of Debauchery

Yesterday, we tried to finish a map with 4 players (not counting 3-4 AI opponents), but some people only lasted until 4 am, so we postponed it until next time... In general, almost the entire map has been explored, and the army is prepared; battles should start soon. There are 4 factions, each playing for themselves, although there seems to be a verbal agreement, so it's 2 vs. 2, but in the end, everyone will still have to be killed... So, who will win? Dungeon, Necropolis, Sylvan, or Tower? :O
P.S. And yes, next time, it's better to create maps without water.
