 A dream reveal to Vala Morgan Lefay s clues to three planets must be combined to one Stargate address containing symbols for each, and only one qualifies- when they arrive, the local medieval society tells them a week earlier Ba al was there, and warns nobody ever returned from the quest. The arrival of an Ori force to impose conversion convinces the local library s guardian Orsic, who shows a parchment with cryptic instructions for the Arthurian quest based on five virtues, to help them look for the Sangrail. The first obstacle is a maze through a time distortion field, which leads them to Ba al, already trapped for three days by a chest which contains nothing, but releases them if everyone puts something in it. Daniel then realizes Orsic is not a local but a disguised Ori, and indeed it s Adria, who decided to enlist them since the prophecy requires searchers of pure hearts, so they solve the next riddles together, practicing each of the virtues...
