Sea of Thieves Season 21 adds Parley Pennant and free weekend

What happened

Rare announced Season 21 and a free weekend on September 16, ahead of the September 17 start.

The post details Talk Like a Pirate Day rewards and a Parley Pennant.

The practical change: Install during the stated window and equip the pennant from the flag box if you want to signal a conversation; check event terms in-game.

What is confirmed

• The free period has the stated UTC start and end times and requires no Xbox Game Pass subscription for online play during the event.
• The Parley Pennant is equipped through the flag box and informs nearby ships of a wish to talk.
• Using the pennant during the event can earn Parley Proficiency Sails.

What this means for players

New players have a limited window to try the game.

Existing crews can use a specific signal before approaching others, although other crews may still act unpredictably.

What is still unconfirmed

The post does not guarantee every region's storefront download timing, that a signaled crew will cooperate, or the final requirements of later season events.

What to do next

1. 01
   Check your platform's current offer.
2. 02
   Equip the pennant if appropriate.
3. 03
   Read the live event screen for reward requirements.
