Sylvie and I played the final (and quite climactic) episode of our second season yesterday evening. Here are the two-line blurbs of the last four episodes - see this post and this one for the first nine.
Episode 10: The Walls of Troy
Lady Penelope and her companions never found the Trojan War - but they did have a most interesting trip, complete with temporal phenomena and metaphysical dilemmas...
Episode 11: Phantasmagoria
Summer 1816. Lady Penelope meets Lord Byron, the Shelleys and a few other tormented souls in this dark romantic tale of revenge, melancholy and psychic infestation.
Episode 12: The King and the Land
Lady Penelope returns to the Avalon Project to attend a royal wedding - only to discover that Excalibur, the key to mankind's future, has been stolen by the lords of the Otherworld.
Episode 13: The Sun of Blood
Lady Penelope forges an uneasy alliance with her half-brother Mordred to defeat the power of the Sun of Blood - and prevent the rebirth of their mother, Morgaine the Witch Queen.
