The Barbarian

The Barbarian is a character in Reigns, representing as the ruler of the Eastern Baronies. He can be charmed or offended by the player's choices during gameplay.

Speaking to The Barbarian will not alter Church, People. Military, or Economy.

He apparently becomes the leader of the Eastern Baronies after they unite under his banner.

The Barbarian speaks a different language than The King, but also uses hand gestures to try and get his point across; Due to this language barrier The Diplomat will try to translate what The Barbarian is saying to the player, but The Diplomat seems to be not the best at his job.

A specific combination of cards has to be used to result in an alliance between the player's kingdom and the Eastern Baronies; You can acquire this by using The Diplomat's strange translations to your assistance.

How to get an Alliance with The Barbarian and the Eastern Baronies.
Below is a list of all "positive" responses that should assure you an alliance with The Barbarian."'Igolo dal brezou. Shabale. (he points at his face) Shabale, shabale.'"> Look at The Diplomat; > Sigh"'Hagadam dolo. E dolo pragon. (he mimicks riding a horse)'"> Give him a horse"'Progodu tyo damno. (impenetrable look)'"> Look at The Diplomat; > Tell him, "space is the fool's sword.""'Laga dolo. Laga dolo... (looking sad and depressed) Gabo lo.'"> Look at The Diplomat; > Angrily bang on the table."'Groro da? (he removes a large piece of meat from his coat and offers it to you)'"> Look at The Diplomat; > Tell him my castle is not a dump."'Zgando agamane hirim Gabo! (gentle laugh)'"> Laugh

Once a final interaction (which I couldn't find the full text to, sorry!) containing "Zgada" appears, look at The Diplomat and select "All Right", and you shall have your alliance.
