Starter Set, Deity Ideas

So, as a result of several of my character's backstories and several players having run the campaign before, I have made considerable adjustments to the Starter Set campaign concept.  I've attached my working concept map with connections below for anyone to peruse, but I will include the key points and some questions for anyone willing. I've got understanding of just enough lore to make things dangerous, but missing key connections

Significant Points:

The enemy side is on a 2 way race for Wave Echo Cave
Lolth Servants and remnants of the Shade Enclave both seek to control the Cave to supplant Shar or Lolth as god of magic.  
Chardalyns have been found in mass amount deep into the cave, with extremely powerful magic even deeper
Lolth Servants are using Black Spider/Redbrands/Goblins;  Shadow Enclave is using Orcs/Skairixus (PC dragonborn clan)
Independent NPC rogue clan is eyeing Skairixus movement
Titania has ordered the god Skerrit to assist his servant druid in preventing the upset in magic that could occur


A few questions:
First off, any additions/changes that sound interesting to anyone?
For both Lolth side and Shadow Enclave, what are some good enemies/creatures to utilize?

And finally, for my Druid, what interesting Fey creatures could he present for the Druid to obtain the wild shape of?

I'm not worried about sticking to 5E specific themes, so feel free to bring the suggestions or critiques.
