When I bought the Dryad Queen from Greebo Games, I also noticed how many amazing undead miniatures they make and I bought these two without really knowing where they would fit in my campaign.
Fast forward to now where we are closing in on the first big conclusion of the campaign, it is clear our arch enemy, the necromancer Varona Stillborn is equally obsessed with the elementals.
So turning these two undead champions into elemental based Deathlocks matching my Ice & Snow and my Lava Inferno gaming board sets, seemed to make perfect sense.
