A elf steps over to you "lay down" the bed is already surrounded by a rather intricate spell circle, some sort of gem spell focuses at each of the 30 star points, The elvish woman begins to sing in some sort of strange language, presumably elvish. The song is a beautiful melody that seems to simultaneously soothe your pain and make your skin crawl...literally, your deeper wounds close into manageable ones while your smaller ones heal completely. After that the elf moves away "Someone will come along to bandage your remaining wounds."
(I did forget to say this, it really isn't the words in a spell that matter, it's the meaning behind them, theoretically spells can be written in any language, some older beings choose to cast in dead languages so that their moves cannot be easily deciphered, maic may be taught publicly, but powerful spells are still coveted and guarded jealously)
