WOW!
What a riveting story . . . and a ship I'd never heard of or even considered, but I guess that Tom and Minerva would have been at Hogwarts at about the same time, though, wouldn't they? Oh dear, did I just see a plot bunny poke his nose out from under my bed and sniff . . . oh dear , oh dear, we are in troublt now . . HE!HE!HE!
Only one slight boo-boo: "The angel begins to take place before you" I think you meant to use the word shape and you used place in the next sentence . . . sometimes our brains are a step or two ahead of our fingers.
Otherwise . . .bloody brilliant!
A very compelling story :) I actually enjoyed the read. Thank you for sharing it with us.
