Dragon round.pngThe Thrall is a unique unit of Dragon clan


Nidhogg clan is merciless and relies on slavery to prosper. As slaves, thralls do not require Buildingcapacity.png housing, consume 33% of what an usual Villager do, but produce 50% less (with few exceptions) and might revolt if they have the opportunity.

Like regular dragon civilians, Thralls can travel and fight in neutral territory and don't get production penalty if wounded.


  • Starting bonus : two Thrall.png Thralls. Slaves.png Thrall maximum number is 33% of the player current population (rounded).
  • Fame.png 200 Fame bonus : Five more Thrall.png Thralls are obtained, it can bypass the thrall maximum number.
  • Buying from Longship Dock : It has a starting price of Kröwns.png 40 Kröwns, each purchase augmenting the price by Kröwns.png 50. Price slowly decrease at a rate of 4 Kröwns.png / month until it comes back to Kröwns.png 40. Slave trade knowledge allows to lower this minimum.

Slave Trade

Thrall.png Thralls are 50% cheaper, and minimum price is also reduced by 50%.

Role in economy[]

  • Thralls can be sacrificed in the Sacrificial Pyre in order to gain Dragon Essence.png 3 Dragon Essences, against Dragon Essence.png 2 for regular citizens.
  • Per default, they will act as villagers and gather Food.png 2 Food.
  • Specific Knowledges allows the player to affect thralls to other buildings, making them working like specialized unit. They produce exactly half of the regular unit production, except for the Longship Dock where they produce Kröwns.png 1 Kröwns, the Fisherman's Hut (Food.png 2 Food), and the Hunter Lodge (Food.png 2.25 Food).

Blood, Sweat & Tears

You can assign 2 extra Thrall.png Thralls to production buildings.

  • Thrall production is affected by upgraded buildings and plain bonus such as forest, but not by tools or economic lores.


If the player Population.png population drops below Slaves.png thrall population, Thralls will instantly rise and become neutral entities fighting into the player territory. Then, the only way to get rid of them will be to kill them.
