Domestic Respite
Caleb, Fjord, Yasha and Beau arrive home to see Essek standing outside the Xhorhaus. He takes not of the large tree growing out of the roof. Caleb says that they're making themselves at home, which Essek can see. Beau asks if Essek wants to stay for dinner, but he turns her down since he has research to do. Caleb asks what he's researching, but Essek just says that it's his specialties. Yasha ends up (awkwardly) asking where Den Thelyss lives, and Essek tells him that most of the den lives in the Lucid Bastion or the Conservatory. Caleb asks if those are the main avenues for learning Dunamancy, and Essek says that they are the only way. He asks why Caleb wants to know, and Caleb tells him that he is very interest in Dunamancy, wanting to learn. Essek tell him to show him something impressive, and he creates the giant cat paw, amusing Essek. He asks what Caleb wishes to do with the magic he learns, and Caleb says that he wasn't taught in the traditional sense, but is interested in the arcane of Xhorhas. Essek says that many people are interested in Xhorhasian magic. Caleb tells him that the Empire is messing with Dunamancy and he wants to understand so that he can help prevent that. Essek asks if he's busy now and Caleb shakes his head no. He asks if he can enter the house, to which Beau become offended since she asked twice and he said no. He says that he wasn't asking her and turns to Caleb who uses the cat paw to let them into the house.

In the study, they pull out their spell books as Essek offers to teach Caleb some spells. He asks what Caleb is interested in Dunamancy and asks what he's interested in. Caleb says that he is interested in fate and time. Essek teaches him the spells and is interested in what Caleb will do with them. Caleb says that he'll need time to perfect them, but thanks him for such a great gift. Essek tells him to remember it, since he may call in a favor for it, which Caleb agrees.
