I’m looking for a dark side artifact

A while back my group went into a dark side tomb and found a helm (helmet) that belonged to a fallen Jedi.

Basically it granted a rank in force powers but was possessed by the spirit of the dark Jedi.

Recently I’ve been reminded of it but I can’t remember the name. It looked like a grey helmet with long prongs coming out each side giving it the shape of a giant T.

I once had the stats up but I’ve long since lost them and I was hoping anyone could point me in direction of it.

Edit:

Found it.
