Dark Elf priestess cult ideas

[Lloyd Dupont 100]

Background:

I am putting my Dark Elf down... They are loosely inspired by all the dark elf lore around but just loosely!  

Those Dark Elf are long lived and practitioner of magic, also slavers, occasionally planar traveller and generally a scourge on the other races and even other Dark Elves.

Their main goddess would be, hey why not, named Lolth!   But I don't care much about existing Lolth lore, I already called her the goddess of Nightmare.

I gave them the following

Cult Idea for discussion:

Cantrips:
Dark Wall, Demoralise, Second Sight

Blessing

Cloak of Darkness (vs magical attack)
Summon Nightmare (sounds good, but what the heck is a 'nightmare'?)
(last I was thinking...) maybe Mass Demoralize?

Nightmare?
I was thinking could look like a black cloud with dark lightning tentacle? Or maybe a deadly spider warm? (i.e. they are small and numerous and bite hard and poisonous), Or maybe an invisible tentacled fighter?

Care to offer some more precise stats on those 'nightmare'?!  

I guess we are missing a demon Entry in the bestiary!

There are Dark Elves already described in the Shade Land supplement, available on DriveThruRPG. Not exactly like yours, but similar.

Oh.. it also as Giant Insects statistics, or so I heard!
I was wondering what it was.. thanks for telling me where to find it (DriveThruRPG  )

Might get it.. it's not that expensive and I am sure there could some cross pollination in terms of ideas
