1400 seems fine except for the one big hurdle being "Þ", which I feel like I'd seen at some point but did not recall. ("ȝ" is useful but that's somewhat easier to guess and not too critical. "ſ" is also easy to guess and I'd seen it before.)

1300 is noticeably harder and needs some iterative refinement, but once you rewrite it, it's surprisingly not too bad:

> Then after much time spoke the master, his words were cold as winter is. His voice was the crying of rauenes(?), sharp and chill, and all that heard him were adrade(?) and dared not speak.

> "I deem thee(?) to the(?) death, stranger. Here shall you die, far from thy kin and far from thine own land, and none shall known thy name, nor non shall thy biwepe(?)."

> And I said to him [...]

1200 is where I can't understand much... it feels like where the vocabulary becomes a significant hurdle, not just the script:

> Hit(?) is much to saying all that pinunge(?) hie(?) on me(?) uroyten(?), all that sore(?) and all that sorry. No scar(?) is never hit(?) forgotten, not uuhiles(?) is libbe(?).

It gets exhausting to keep going after these :-) but this was very fun.
