Heroes 5.5 WarGame Edition - Tactical Edition.

For me, Templars are an order on planet Earth, and Disciples got something mixed up. Then, a Reanimator is a Reaper, a Reaper is a Necromancer. Agroila can be replaced with Wayer or Erazial (or was he killed off?). Instead of Shadia, use Ilay. Dwarves: Wolfsten as the engineer, Brand instead of Erlin, Erlin instead of Wolfsten. Tolgar can be replaced with some dwarf from 5.5. Necropolis: Arnel can be replaced with Anastasia's daughter from the sixth game. Humans: Isabel is alive, and Duncan is there, and there are a couple of other red heroes; you can take the guy from "The Mandate." Also, I would review all the cutscenes. For example, in the "Duncan" mission, a captain of the Knights is mentioned, and Zehir is always talking to some mage (maybe Narhiz). In the original mission for the Necromancer, Lich Ishkibal is mentioned. On the maps, you can see that Erlin is a Warrior.
