The Sword Of Triton Has Been Unleashed

[Tiberius Fireskull]

hehe... looks kinda like garbage... I mean, I'll probably redeem it on my little pirates, but not on my two big ones. I don't think it'll be much use for them. Although I agree that this sword is garbage, it probably will lead to something. Perhaps something big. Very big would be nice.

i might be able to make more sense of the riddle
"This sword holds far more power than meets the eye, for when a royal bow breaks water, ye shall know her name and that of her enslaved crew."

far more power than meets the eye=something still to be added to it
royal bow =navy/king/queen annes revenge
breaks water=is released/ship launched
ye shall know her name=what it actually is/what it actually does
and that of her enslaved crew=new enemies (zombies)/something connected to the sword eg more swords or more of blackbeards weapons

i think the most likely is

this sword has stuff still to be added to it when on stranger tides is released you will see what it actually does and the zombies will be added

but thats only a guess

also posidon was greek god of the sea not triton triton is his son and messenger
