I *love* your writing! That passage was reminiscent of a scene in “USS Seawolf” by Patrick Robinson (sp?). They didn’t have Blgthrgths, though.
Strangely, I often get asked ‘what drugs have you done” when people read that stuff.
No drugs, all natural weird here.
You should meet my parents.
That explains everything.
I see Blgthrgths as being highly enraged flying towels of one sort or another.
They land on your head before screeching in fury.
No real damage except the startle factor of having some enraged flat floppy creature wrap around your head and begin howling.
