The Dragonspine Terrors

Diluc is invited to spend some time with Aether and Paimon in the cold region of Dragonspine, which has recently had a major temperature decrease, according to the floating pixie. Diluc is the only one who seems to be relying purely off his own abilities, except the necessities needed for traveling in Dragonspine. Will that and his pride be enough to survive this trip, though?
