On the oblivion expansion pack the shivering isles how do you get through that tree door that leads to a burrow cause its locked and no matter what I do I can't get it to open

If it's the one I'm thinking you have to kill the two spiders outside of the tree and one has felldew on him and you must take that to get into the tree and keep finding and taking it while in the tree. So look for felldew and take it and you should get in.

Ill try it ty

Nope it didn't work have you got any other advice for me
