Lol, not that kind of Diadem! The Diadem is a W101 based fanfic by me, about Sylvia Drake's diadem. (Ok, yeah, so maybe it is about a Diadem.) The main characters are Caroline Dawnrunner, Rebecca Duskglade, Aedan Thunderpyre, Travis Spelldust, and the Cold Master.
These are all the writted Diadem chapters so far.
The Sprites' Secret
The Kraken Returns
The Frost Submersion
The Vault of Ice
The Bed of Ice
Secret Lies in Death
Those are mostly all the chapters so far. Stay tuned for the next installment!
