Explore the Birdman Mountains as a halfling, half-harpy, kestrel, strix, urisk, or xax. Visit the markets of Harhold, the lost settlement of Krikoym, the winding passages of Old Deeps, or cursed Ruin Spires. Select new options for bards, bloodragers, druids, fighters, hunters, oracles, sorcerers, wilders, and wizards.
