Making RPG proposals in Rohan (and the Shire)-- a tutorial

[Nonesuch]

I've decided on the premise for my RPG. There's a single event which impacted upon several characters in LoTR but is given relatively little discussion by Tolkien. All we know of this event comes from two entries in the Tale of Years and a paragraph in the Appendices. This event is the kidnapping of Celebrian, daughter of Galadriel and Celeborn, wife of Elrond and mother of Arwen, Elladan and Elrohir, and her rescue by her sons.

I'd like to take a stab at telling this tale at length through an RPG. I'll fill out the proposal form and submit it soon. Thanks to everyone for their suggestions and help!
