Triggering a hidden mission

Blacksail pondered before answering to Sheyan’s inquiry.

"I can only say that be a fair and bold speculation, cap’n."

Shayan glanced at Blacksail, before sinking into deep thought.

"You haven’t told me the most crucial detail of this thing – the fruit’s name and uses."

Blacksail revealed a troubled countenance as he replied.

"Cap’n, this be all the knowledge I know, besides I am just a pirate. Oh blimey, tis’ be an exceptionally rare seed to fetch a good booty at Tortuga."

Sheyan smiled gently.

"Somehow, I feel your knowledge is rather profound, you resemble an alchemist."

Blacksail’s expression turned even more awkward.
