The Golden Pearl

[...] My heart is pumping. The water is calm, the crew is sleeping, I am wide awake. I finally deciphered this map. Ill will venture into this underground maze with my crew tomorrow. These creatures... Little is known about them around here. All I know is that they swim the deep waters and find extremely rare golden pearls. I reckon I will be the first human to put my hands on one. I will show them I come in peace and that I am willing to make a fair trade. 
I will update this log tomorrow.
