Well, here goes.

Short version of real name:

Your fairy is called Hex Goblinspider
She is a bringer of riches and wealth
She lives in places hexed and tainted by black magic
She is only seen when the dry seed cases pop

Don't like that!

Long version of real name:

See above!!!

Middle name and surname:

Your fairy is called Gossamer Reedspider
She is a panpipe player and enchantment singer
She lives in spiderwebbed wonderlands and insect grottos
She is only seen when the dry seed cases pop

Much nicer!

Mudcat name:

Your fairy is called Water Iceglitter
She is a bone chilling revenger of widows
She lives near bubbling brooks where Lords and Ladies and Cuckoo's Pint grow
She is only seen in the light of a shooting star

Not another one!

I think I'll use either my Mudcat one or the one with my middle name.
