i can no longer go to the tomb and the quest finder is gone please help me.
Are you looking for Sylvia Drake's tomb?
Sylvia Drake's tomb is in The Necropolis. After you talk to Cyrus Drake, you enter the portal for The Necropolis. Her tomb is right near the portal after you go through it. Press "m" to look at your map. You will see a picture of "The Crystal Guide". Sylvia's Tomb is in the lower left corner of the map. It looks like a little blue building.
The tomb is just inside the Necropolis. It's in the lower left corner of the map and looks like a small blue building.
If the portal to the Necropolis (by Professor Drake in the Basilica) isn't active, then you need to activate it by going through the Plaza of Conquests until you reach (and go through) the door to the Necropolis.
