zig-zag
It seems to be read in a zig-zag pattern. Word breaks and punctuation have to be added in, and the colloquial speech ("be" is dropped from "beneath" and "beware, at least; "ye" is used for "you;" stuff like that) threw me for a bit.
[sblock="more information"]Start at the top left "f," then go down and to the right to the "o" then up-and-right to the "r." Continue to the upper right "d," then straight down to the "i" and go back left. When you get to the "n" right below the starting "f," you go down to the next row, which starts with a "d."
You keep going back and forth in that interwoven zig-zag until you have all the letters. You then put in spacing and punctuation to make it more legible.[/sblock]
[sblock="solution"]For twenty years did Kurrigan sail, sending sailors to their briny graves, making orphans cry and widows wail for men, whether craven or brave. Blackheart's gold is hidden well. You'll find it 'neath the Hangman Tree. Go seek ye the Throat of Hell from 'twixt the Teeth of Umberlee. 'Ware the traps and tricks he laid, and avoid the diamond's shine. My final debts are fully paid now; at last, revenge is mine.[/sblock]
