What Lies Beneath is the twenty-second episode of the first season.
The Defenders stop to help a caravan of refugees fleeing the Obelisk-ravaged countryside for the safety of the Arboth. Brackus and his Mercenaries also descend on the village of Arboth, having identified it as the source from which the Pure Stones were carved. In the midst of this, Seth deserts the Defenders as his merge transforms him into something he cannot come to terms with.
