Sacrificial Pyre is the pyre at which you can sacrifice your Vikings and (primarily) Thralls to the gods in exchange of Dragon Essence, mystical essence of Clan of the Dragon. Through this building, any unit (except for the clan's Warchief, enthralled Jötnar or Bláinn, Spectral Warriors) can be sacrificed. Sacrificing a unit will earn a certain amount of Dragon Essence depending on their type:
- Sacrificing a regular (non Thrall) unit gives +2 Dragon Essence.
- Sacrificing a Thrall gives +3 Dragon Essence.
