George R.R. Martin, the author of the "Song of Ice and Fire" books that are the basis for HBO's "Game of Thrones," will kill off a character named in honor of a fan who contributes $20,000 toward Martin's efforts to raise money for a New Mexico wolf sanctuary, according to The Hollywood Reporter.

The contest's page at Prizeo says: "There is one male character and one female character available. You can choose your character's station in the world (lordling, knight, peasant, whore, lady, maester, septon, anything) and you will certainly meet a grisly death!"

Martin has reportedly already raised more than $220,000 since the contest began Thursday.

"Other prizes up for grabs [include] having breakfast with Martin ($15,000), tickets to the 'Game of Thrones' season-five premiere ($7,500) and even Martin's trademark hat ($7,500). There are also lower-ticket items, such as a thank you e-card from Martin ($25) and a T-shirt ($50)," THR reports.

The story notes: "Martin and his wife, Parris McBride, are avowed wolf lovers and say the money will go toward improving the habitats at the Wild Spirit Wolf Sanctuary. It will also benefit a local food pantry, The Food Depot of Santa Fe."
