The reason Zankou and other demons are always after the book of shadows is because it would give them not only the power it has but other information such as how to kill their enemies, get to the elders, and hurt other good magical beasts.
he would turn the book evil and probably become the source of all evil
They kill him and they also fake their deaths in the process because the homeland security are onto them.
The first seer, the one who appears in Season four and who is vanquished when she tries to steal the son of Phoebe and Cole is just named 'The Seer' and has no propper name. The Seer from Season Seven, however is names Kira and becomes a friend of the sisters, she even asks them to turn her human in return for information and a look at the Avatar's Utopia, which she gives to Phoebe. Unfortunately, Kira is murdered by Zankou just before the sisters can turn her human, and that is what really gives the sisters the push to go to the Avatars.
There are numerous demons that the Charmed Ones encounter throughout the series, including The Source of All Evil (Cole Turner), Barbas, Shax, The Triad, The Seer, Zankou, The Oldest Demon, and many others.
The most powerful demon on the show "Charmed" was Cole Turner, especially in season 5 when he was INVINCIBLE, because he could not be vanquished by any power, he had strong powers from the Demonic Wasteland, and he was the smartest demon the Universe had ever seen, or heard of. Second was Zankou because the Source feared him and needed to lock him away in a magical prison because he could not be vanquished by any force, the Charmed Ones needed to vanquish the Nexus while he had it so they could kill him, and his powers were unbeatable by anyone. Third was the Tall Man because the Source had to lock him away in a magical cage, made by the Seer, because he feared him and there was no known way to vanquish him, he had unknown powers and abilities, and it took the Source's Heir to eventually kill him. Fourth was the Source because he practically ruled the Underworld with countless demons by his side to do his bidding against the Charmed Ones and other evils, he sent his personal assassin, Shax, to kill Prue and he succeeded, and the powers and force he had were astonishing. Fifth was the Seer because her plan to get the Source's Heir was astronomical, the way she used her powers and the choices she made against the Charmed Ones and the Source were unexpected and unstoppable, and she could only be vanquished by the uncontrollable powers of the Source's Heir in her womb, once and for all.
