Mine are rather boring and not clever. Basically, I followed racial npc characters in the lore, then added my ‘Dhae’ moniker. For example, for my Night elf druid’s name, I came up with Dhaelereth. Named after the Night elf, Delaryn Summermoon (Captain of the Darnassian City Guards during the War of Thorns) and from the ancestral line of Night elves, the Chief Telemancer Oculeth (chief teleportation inventor and engineer), who is a Nightborne.
Plus, it helps me remember who’s who in my character inventory. lol
