So im at the throne room and it has a spiral staircase that is blocked and in the other room it has the bird fish and snake slider things but i don't know the combination. Can anyone help me find where it shows you the combination or can you tell me the combination.

it wont let me turn the stones can you turn them?

if this is the one that i think it is

there are 2 levers one on either side of the throne(s)

one set of stones (heads holding stones) gives you the combination.

flip other lever ... opens another room.

do combination backwards and the grate will open.
