Game description from the publisher:
Prepare yourself for the conclusion of the Secrets of Oldtown cycle of expansions with Here to Serve for A Game of Thrones: The Card Game. The sixth and final Chapter Pack introduces three copies each of twenty never-before-seen locations, attachments, characters, events, and two plots, spread over all six of Westeros' Great Houses. These cards forge the final links in your Maester's chain, transforming your Maesters into invaluable allies on your path to victory.
Forge your Maester's chain with the Valyrian Steel Link and Brass Link attachments. The theme of these chain links is card advantage: while Valyrian Steel gives you the ability to draw more cards, Brass Link discards cards from your opponent's deck and denies him resources. Here to Serve also features two new plots that boost your strategy, allowing your characters to attack and defend without kneeling during intrigue challenges and raising the claim on intrigue challenges you initiate. Here to Serve introduces a wealth of new deck-building possibilities, especially for decks that feature Maesters.
