Half-elves are very common in Lastland society currently. Many of them have been born over the last 200 years due to the elves attempt to spread their culture and bloodlines. Although many of the older elves have taken an extreme dislike to all half-elves due to their origins, younger elves have no problem with them and in fact may well have multiple half-elven children even if they are only a hundred years old.
Humans’ relation to half-elves is complex. Many humans, especially those that come from wealthy backgrounds, have a half-elven half-brother or sister. Having a half-elf in the family has come to be seen as a status symbol for humans and half-elves tend to be seen through that lens, for good or ill: many humans for poorer backgrounds view them as posh good-for-nothings, the spoiled children of privilege, while others view them as paragons of refinement and culture. Other races tend to have a less complex relationship with half-elves on the whole.
Half-elves are faced early and often with these views and either embrace them to become refined members of the intelligentsia or go the opposite direction to embrace the tough wilderness of the Lastlands and become more focused on the outdoors and adventure, avoiding cities and ‘high culture’ and largely ignoring their human or elvish heritage (or both). The current fashion among this faction of half-elves is to slice off the tips of their ears to make a crescent shape as a statement.
