How does one get into the second story room in Alagner's storeroom
to get his notebook?  I have opened every metal door excpet one: the
second door on the right of the outside wall switch.  I have also
tried all of the transporter platforms in the building.  I have used
telekenisis to open the second floor door and read the notebook, but
I cannot take possession of the notebook since I am on the first
floor.

How does one actually defeat the creature firing the lighting bolts
in the tetrahedron room?  I have the ring on which Penumbra mentioned
to protect me from the bolts and I am the only one of my "party" in the
room, but each time I try to swing the glass sword or another weapon
at the tetrahedron, I miss.  Do I have to get inside the "rock pile"
where the tetrahedron is before I can destory it?  If so, what is the
trick to getting there?

Thanks in advance for any help!
