Fuzzy Memory

[Naiad780]

Hello!  I'm going to post a vague question based on a vague memory in the vague hopes that someone has a spark of information:  are there any known communications from a group called the Diehl'im?  Not sure of the exact spelling, but it sounds like that.

I'm sorry I can't be more specific--it's just a really fuzzy memory I have that's been nagging me.  It feels "real," so I thought I would check.  Thanks.
