Cof L49, p75 hc: "No hallowed skein of stars can ward, I trow"

[Mark Kohut]

Trow = to know, think, believe.

A--and (more Shadowingly): 
Like the troll of Scandinavian legend, with which the trow shares many similarities, trows are nocturnal creatures; venturing out of their ‘trowie knowes’ (earthen mound dwellings) solely in the evening, often proceeding to enter households as the inhabitants slept. Trows traditionally have a fondness for music, and folktales tell of their habit of kidnapping musicians or luring them to their dens.

Does anyone link "hallowed skein of stars" with Driblette's, then Oedipa's planetarium metaphor?
