Extend scenario in Dragon of Dream

1 post / 0 new
I am translating to 4e "Dream" in Dragons of Winter(3.5e) scenario.
I want to extend scenario in part of Waylorn's episode in "Dragon of Dream".
Simple traslating is not interesting.

I examined about Waylorn in Lexicon of dlnexus.com.

|Waylorn, along with some other Heroes, which included Dereg
|Raynhold, fought bravely against Sylvyana and her Wyvern and Wichtlin
|minions defeating them.

Can someone please tell me about this episode in detail.
how about Novel or Source book?
