I haven't touched my Dark Eldar since they were still using the 3rd edition codex (I was out of the hobby altogether for the last 4 years).
Here is a pic of my Succubus, which I converted from an old Dark Elf Sorceress as I don't want to pay $23 for a single model with no options, which will end up looking like everyone else's Succubus.
There's also a pic of her leading my Wyches. These I converted back when the 3rd edition of 40k was still in place. I hated the old Wyches, so I converted them from Dark Elf Witches.
