Historical Allies (HA) is a feature which was introduced on the 15th August 2024 (beta server), and released on 24th September 2024 (live servers). Once a player has researched Roof Tile Houses (Iron Age), an entry building next to the Antiques Dealer becomes accessible, from which various historical figures can be assigned into specific buildings, offering a variety of boosts.
Overview[]
In the Hall of Legends building you'll find all the necessary information about acquired allies, such as their rarity, type, level and whether they are already assigned to a building or not.
Acquisition[]
Once the feature is unlocked, the first Ally - Spartan Soldier - will automatically be added to the Hall of Legends. More Allies can be earned through various events or Rival Challenges.
Usage[]
For an Ally to be placed in a building, such buildings need to have an 
Ally slot with a matching type. For example, a Military ally can only be assigned to a Military slot. Once the slot is occupied, it changes appearance into a 
Full Ally slot. Allies can be freely exchanged between buildings or with another ally. On top of that, some slots may be rare slots, which allow only rare Allies to be slotted.
Allies[]
Each Ally can come in different rarity. Depending on the rarity, their effects are greater the higher the rarity, and also rarer allies can reach higher levels. Currently it is unknown how they can be leveled up.
