Released as part of the Emperor Edition or Founder Edition of Endless Legend, this Add-on includes the Geldirus minor faction, the Drakken hero Researcher Namkang, and the "Song of only Ice" custom faction trait.
Initially part of the Founder Edition of Endless Legend, this add-on was added for free to all versions of the game during Endless Day 2016. It adds a re-skin of the Vaulters faction, the Mezari.
