The Mercenary Portal is the means of summoning Heroes for your cause in Dungeon Keeper 2. It was added to the game with the 1.2 Patch, but only appears in some skirmish maps and makes no apperance in Campaign mode. It serves as the entry point for all recruitable Heroes except the Lord of the Land, The Princes, King Reginald, Dwarves and Stone Knights. Like ordinary Portals, it allows 15 creatures through the first one claimed, with an additional 5 creatures for each portal claimed afterwards. The Mercenary Portal is a 3x3 room.
