“Magic Runs Deep”
The setting
Nauctis is a new plane and a new starting point — Wizards described it as the opening of a multi-year story arc, which makes this the set to be there for if you like getting in on the ground floor of a story. The pitch is a journey that starts in calm shallows and gets more dangerous the deeper it goes, with something described as an apocalyptic danger waiting at the bottom.
The cast is the deepest merfolk-adjacent lineup Magic has put in one place: merfolk, homarids, sharkfolk, squidfolk, seals, humans, and deities who rule over the plane. The plot hangs on two warring kingdoms and a group of unlikely heroes caught between them.
