Light and Dark (Charmed AU)

Guardian: A witch who died but was allowed to keep their powers to better protect and guide powerful witches. Similar to a whitelighter.

In 2003, the Guardian of Wyatt Halliwell was captured by the new Source.
A few weeks after she was saved, she found out that she was pregnant.

Christopher Perry is from the future and while he does have a connection to the Halliwell family, it's not in the way you'd think.
