Eggies have the semi-strong Pharoah, who respawns when he dies. There is a tech that allows you to have two. They can also make priets, who are weak in atatck, but can heal. Set's pretsts can convert.
The Greeks can make 1 new hero every age. They are very strong, and have a nice HP, the later ones also have a special ability. Once 1 dies, you can make him again.
The Norse can mae hesirs. They are cheap, but aren't very strong. Ragnarok turns all villies/dwarves to special heroes.
