Grandmother Spider's SpiritWeb

Howdy folks! I have been Wiccan for the last 8 years and regretfully confess I haven't practiced the belief for approx. 3 of them. Now I come to the table in need of assistence and (gulp) help. My fiance' has a brother who for as long as he can remember has been "haunted" by visions and dreams influenced by a being that (from my understanding) calls itself "Archaos" (Ark-a-o-is).

I was reading one of my books and it started to list gods and goddesses, But in one of my other book it say we just worship the landy and the lord so i am a little confused help me please
