Available to Norse, Egyptian and Atlanteans cultures. Each age unlocks every myth unit and technology available for that cultures for that age, regardless of the minor god.

 NORSE

 Now, you can control Valkyries, trolls and Einherjar's in the classical age. Forseti's Hersir upgrades, Freyja's Cavalry upgrades, and Heimdall's wall upgrades are all available at the same time. It effects Major Gods as well. Thor armory upgrades are available to Loki and Odin now.

Create your super frost Giants with Skadi, and Hel's Giant upgrades!

 EGYPTIAN

 Priests can empower  and convert wild animals regardless of the major god.

 Now, you can have a son of Osiris and an Avenger at the same time!

 ATLANTEAN

 Atlantean major gods will keep their unique bonuses since most of these are hard-coded.
 Since Atlanteans have more God Techs then any other culture, I put the two Leto upgrades on top of each other. One needs to be upgraded, to research the other. Eye of Atlas is also located under the Celerity age tech, I consider moving some of them to Town Center, but I think that they work better here.
