Some of these are probably quest so don't answer them if that's the case, but...

There are a number of apparent doors in the mud that don't seem to work like doors.

The ones I'm thinking of are:
A) Door in the gnome village in violet woodlands.
B) Door by the elemental/dagger spec, in ruins of delar tol
C) Door to high priest in temple of sands (araile)
D) door in dra melkur by child ghost

How do these doors open? Where not questy. I think that at least two don't open (a and b). Is that accurate?
