The Aaracokra

Before they get a chance to leave their camp, they are attacked by a giant gray wraith that causes Theros to panic and faint. The party defeats it and questions him, and he reveals that he got the arm - the Arm of Ergoth - from a gaurded location and it's been chasing him since. He is grateful the party defeated it. The party continues, eventually reaching the foot of the mountain that the Stone Dragon is on. At one point, they stumble upon the tomb of Huma and detour so Aaron and Derek can see. Once done, they continue to the base. They decide they'll need to climb it to be able to enter. They end up encountering the dad white dragon, who torments them for a bit before flying off. On the way up, the party has to negotiate with eagles to safely pass through. Afterwards, after some more climbing, Alphy's chimera and him end up getting into a fight over how Alphy is acting and treating it, and the chimera antagonizes several giant bats, leading to the party getting attacked and needing to set up camp again. They continue up the stone dragon, eventually reaching the elbow where they are greeted by bird people, otherwise known as Aarocokra. They inform the party that they are invading their kingdom, and they'll need to come to them to their Hidden Vale to meet the king. The party is taken to him, where they see him tending to his son who is gravely wounded after a fight with draconians. Silvart and Elistan move to assist, healing the prince. The King is grateful, and allows the party to stay. Whilst there, Alphy is greeted by numerous little fluffy Aaraockra kids who are curious about him and his chimera. He is delighted and reveals to the party that he loves Aaraocokra, and his last fiancée was one with adorable kids. He ends up playing with the kids and showing them all his cool, gear, explaining their journey, etc. Cinder grows slightly less skeptical about Alphy from this, and the party stays for the night. In the morning, the King offers to show the party how to access the Stone Dragon and the party thanks him.
