"Essos is an immense landmass located to the east of Westeros, extending into the far east of the known world." (Here, "extending" describes the Essos or does it describes the landmass? )
Having seen this sentence above, I question came to my mind.
Can I use participles to modify the subject of the main clause when there is no connection between main clause and participle clause. For example:
1- "He is a bookworm, living in Canada. (He is a bookworm + He lives in Canada, there is no connection between being bookworm and living in Canada)
2- He, living in Canada, is a book worm. (I suppose, this placement would be more correct)
