-While most units have three levels, not all do. Occasional units (such as <ref>dst=unit_Mage text=Magi</ref>) may have four. Once a unit has reached its maximum level, it may have an After Maximum Level Advancement (AMLA) available to it. The AMLA will modify the unit each time the unit reaches the experience goal, but the unit will remain the same level. The typical AMLA effect is for the unit to raise the maximum HP by 3.  The first AMLA will normally be reached with 100 XP gained (80 XP for intelligent units).  However, gaining an AMLA becomes progressively harder for each AMLA the unit receives, and so it is often more useful to try to advance your lower level units.

 Note that only a small number of units, for example the Necrophage, will actually heal with AMLA effects. Most units just gain the bonus to the Maximum HP."

Likely the most unhinging fact about them, for fact it appears to be, is that they were somehow made from living men - a process about which almost nothing is known, but which can be nothing but nightmarish.
