The heavy trireme has been the war-ship of choice for the Nabrolians, for several centuries. During an aborted attempt to invade the northern lands (and Kur Maeth in particular), a large armada of heavy triremes was captured by the Fourth Crusaders, and have since become the primary war-ship for Kur Maeth. Regardless of nation-of-origin, heavy triremes tend to be coastal vessels with a limited range, and constant resupply issues.

Nabrolian heavy triremes tend to carry several dozen heavy cavalry, as well as two or even four hill giants (which serve as platforms for the Nabrolian priests). Oarsmen tend to be slaves on meager rations. The heavy catapults are often augmented by hill giants throwing stones.

Kur Maen heavy triremes also carry cavalry – usually bonded mounts for the paladins on board. The oarsmen are paid volunteers, consisting of holy warriors from the various faiths. With a massive number of priests and crusaders to draw on, resupply issues are often moot. The heavy catapults are usually replaced by heavy blalistae, however, and the joint work of several clerics. Most Kur Maen triremes are broken down by faith, and each vessel will consist of holy warriors all of one church.

Design
The crow's nests are often platforms nearly fifteen feet on a side, allowing for a large number of archers, spotters, and crossbowmen to rain a deadly hail of missiles onto enemy decks. Usually, the snipers in the crow's nests target officers or important-looking persons.

Provisions are usually stowed beneath the oarsman's benches.

1. Main Deck: The main deck is dominated by six pair of heavy weapons, usually kept under tarp and unprepared for combat. The square sails are used to augment the oarsmen. Additional directional control comes from a conventional tiller, located extreme aft. The cargo hatches make use of moderate cranes built into the twin masts, and can also carry longboats. Ammunition for the primary weapons is stored on deck, with additional ammunition below-decks.

2. Second Oar Deck: Here, the secondary oars are used and stowed. The chain locker for the anchor is located in a storage compartment fore. The cargo hatches descend through this level, as well.

3. Prime Oar Deck: Here, the primary oars are used and stowed. The mountings for the ram are located fore. The majority of the ship's cargo is located here, and can sometimes consists of smaller assault boats when employed by Kur Maens. Additional ammunition for the main weapons is stored here, usually near the ram-mountings.

4. Leader's Quarters: Usually a single cabin, it serves as the High Priest's cabin aboard Nabrolian vessels, and the captain's quarters aboard Kur Maen ships. It can sometimes be subdivided into additional cabins.

5. Galley: With such a large crew and carrying capacity, this is usually where the cooks work to keep the ship fed and watered. Food and water are stored here, as well as additional provisions.

6. Chain Locker: The ship's anchor chains are kept here – usually one on each side. Aboard Nabrolian triremes, this does double-duty as the arms-locker.
