Break the plank

In one methodic motion, Nami threw her weight forward. With a firm snap, the chains binding her wrists broke from the wall. Her knees found relief on the wooden floor of the cellar, and though her hands were still bound, at least she was now somewhat free.

A clamor from the other room signaled that the guard had awakened, and quickly the handle of the door began to turn.

Was there time to hide? No, even if she did, her sudden disappearance would surely attract more guards to join the search. The only choice was clear then.

Picking up the plank still nailed to the chains on her wrists, she waited at the door. As soon as the guard peaked his head in, she struck.

THWACK!

And then again.

THWACK!

And again.

CRACK!

The guard lay **** on the floor, without a doubt not getting up anytime soon.

Nami checked the remains of her weapon, the piece of wood now barely holding together after its violent attack. She dropped it next to the man now at her feet and, made her way through the opened door.

The nearby desk promptly provided her with the keys to her restraints, and conveniently her weapon as well. As the chains fell from her sore wrists, the navigator then considered her next move.

The most direct way to get back to Sabaody would be to commandeer the ship. But of course that would mean either taking out the entire crew or convincing the majority otherwise to join her side.

Alternatively there was the possibility that this vessel had some lifeboats hiding about. If she could sneak away on one of those, she could easily make it back on her own.

Then again, she could simply hide and wait until the ship made port, and from there find another way to return to the island of promise.
