Who is the elf girl on the UE website background video?

There’s a video that played on the home screen on the unreal engine website page from about 2018-2019. In that video, there was a female elf who motioned a dragon to raise its head. here’s the link to the website from 2019 on the Wayback machine: What is Unreal Engine 4

My question is if anyone knows the source of where that female elf with the dragon came from or if there’s a link to their 3d models if it’s available. here’s the screenshot of the scene from the video:
