THE POPULOUS BIBLE
C.53 Reincarnation Site
The Reincarnation Site (abbreviated CoR for "Circle of Reincarnation" or just "rs") is your source of power on each world. The stones of the site channel all the Mana gathered from your followers and you can draw on this power to cast powerful and destructive spells. When you begin a world, a Reincarnation Site will be created and your struggle for supremacy will begin. If the Shaman dies and you have lost all your Followers, the Reincarnation Site will be destroyed and the level will be over. If you die and you still have Followers on the world however, the Shaman will be reincarnated in the Stone Circle after some seconds. You can't cast spells on an enemy Reincarnation Site and the only way to destroy one is to defeat the entire Enemy tribe. Your Reincarnation Site can be used as the starting point of a settlement.
On some levels, namely Solo, a reincarnation site may not be present. In such a level, if the shaman is killed, then she will not reincarnate.
You can sink the land where the reincarnation pillars are, but the pillars will not sink. When a shaman dies and reincarnates there, she will create land - therefore, it's kinda useless to try to sink a CoR.
When a shaman is reincarnating, she will expel a ring of magic on enemy units who are standing inside the circle of reincarnation in the moment of her rebirth. This will burn any wood piles and cause damage to every enemy units and cause them to run scared like a swarm would (this doesn't affect any shamans, only followers).
On levels where your shaman is trapped in a prison, there is no reincarnation site. Once the shaman gets released but dies, she will reborn where the prision was, but without creating rs pilars.
