Feeling a little lost with all the prequel talk of "the Age of Heroes" and other Westeros history? Have no idea who Lann the Clever is? Why does that Stark sigil we glimpsed from the set look different? Not to worry -- school is in session! The Night's Cast is your visiting maester for a couple of episodes we're calling Summer School at the Citadel, in which we dive into any and all Westeros (and some Essos) history that might be relevant to the upcoming spinoff. This week, join Vanessa, Petra and Samantha for lesson number one on the Dawn Age, early Starks and more.
