I was just moving some items around treasures and I clicked on my Daisy Memento... it has the option to;

"Renounce Loyalty to the Islanders"

What is this?

if you click it you lose access to the islander prize shop.

I was never an Islander?

that's rather odd. I can't remember what mine said. >C

If you were on the Islander side, or didn't choose a side, you can use the Daisy Memento to get access to Port Plunder.

I wish it used to say that when it first came out because I didn't wish to make a renunciation.
