Dwarven Stronghold (d20)
The dwarven stronghold is a multi-level fortified dungeon. It was undoubtedly built to defend one side of the mountain; the other side faces friendly people and has no need of strong defenses. The dwarven engineers built the stronghold near a subterranean river in order to exploit the power of water to build a dwarven wonder: a raising underwater bridge. The bridge is the major defense of the west side of the stronghold. The entire bridge¸ due to a gigantic device working like a dam¸ can disappear under the waves of a mountain lake¸ thus preventing the access to the main portal of the stronghold. Should the enemies manage to go through the portal¸ they would find a formidable line of defense made of ballistas¸ murder holes¸ arrowslits and stone guardians. The stronghold consists of five levels intertwined with a number of staircases heavily guarded. Each level has its own purpose. The level 0 houses soldiers and jails¸ as well as forges and shrines. Level 1 houses more soldiers (these two levels are self-sufficient¸ being provided of kitchens and larders) Level 2 is dedicated to the nobles¸ with great halls of statues¸ an arena and nobles' quarters. Level 3¸ the topmost one¸ is the main temple area complete with the crypts for the dwarven heroes. The last level (-1) is the dam level. Here the dwarven engineers work and keep maintenance of their device¸ also there is the bridge control room."
