Eagle

 Whew, another letter down! On to some simpler encounters, i bring you the eagle, along with the tolkienean giant eagle.

The Everfyre planes are the territory of The Great Eagles. While the majestic birds don't have anything resembling a state, and their ruling body is naught more but a council of elders, it's has been a long-standing custom to ask their permission before settling in their lands, or even more rarely, collecting resources there.
Greedy King Glabradox, unfortunately, stepped all over said tradition and set up several logging operations across the region. These days, any humanoids that trespass without a heavily armed escort are snatched taken to the eagles' home, the Lonely Mountain, for interrogation.

The great eagles of Crownspire train hunting birds for the elves who live in the woods below. However, the eagles are not above intrigue and subterfuge, and more than one falcon has stolen an amulet, hid a letter, or outright attacked their master. When an elven noble ends up dead, their eyes pecked out, an investigation is called for.

The great eagles of Uplands betrayed the ancient oath that they made, and disaster struck. Long ago, the first bird-king made an oath that no kin of his shall ever take part in land-walkers' wars. And yet, the Dark Lord's advance was a threat to the entire world, and so the Eagles flew to war. Their aid turned the tide, and the Dark Lord was defeated once and for all. The day after he fell, the first Eagle lost his mind. In the weeks since, every day the great birds have been going feral. The eagles' now ask the mammals to return the favour - namely, by seeking out Mother Cassowary, a living deity that resides in a land no Eagle is allowed to visit, and petitioning her to lift the curse.
