Playthrough 4 | Aeon's End: Outcasts - Thraxir vs Fountain of Souls

About Aeon's End: Outcasts, from BoardGameGeek:

Aeon's End: Outcasts continues the Expedition system that was introduced in Aeon's End: New Age, which allows players to replay all of the content they own in a short campaign format. After each game, players will receive new treasures and player cards that allow them to become more powerful. However, the nemeses that players will face grow stronger and stronger with each battle. -description from the publisher
