After a talk with @ender-punk i decided to make some headcanons about the "End Endermans"
Im probably gonna make some about the Earth and Nether Endermans later
Well, End endermans, unlike earth or nether, are much taller, and more closely resemble the dragon itself than any other species.
They are pureblood beings, and extremely intelligent, made their own civilizations, have their own language and religion
Coming more to this part of civilizations, they are divided into tribes, each with its role, has its customs and traditions
We also have the most superior classes, which are the Shamans, they communicate directly with the dragon, the protector of the End and their god. they are extremely respected and are usually a leader.
Shamans are also known to carry something precious from the dragon with them, to have a closerelationship with it, usually baby teeth or clipped claws.
But of course, End Endermans are quite arrogant creatures, they pride themselves on keeping their blood pure, no Enderman of the End can breed with any other creature besides their own kind.
and... in some situations... some Shamans fall in love with the dragon, which was scandalous for their religion.
The dragon was a pure and respected being, of great enormity, who should never have his blood stained by another species.
Anyone who had some kind of relationship with the dragon or another species would become an outcast and would be banned from the End..
