I don't seem to be getting anywhere in Cet's tomb. I've talked to the lich, charged the mavin in the black fire and found the Tome of Fire. I find a statue of a sphinx/cat? that I can grab but can't move it. Please help me where am I supposed to be going or doing, I've found a door that requires some key(champion?), where do I go, heeeellllppp.

You have to look for a room with a portal of Isis. Cet will appear and tell you you are lost. But then Kerah will come to help you. Cet casts Twisted master on her so she will attac you. Give her an emty bottle filled with holy water but only if she says she is thirsty. Then go and open the door in the lava with the two Champion keys and met Cet......
