The felt marker is a tool from GruntHack. It is mostly identical to a magic marker, except that it cannot be used to write scrolls or spellbooks; the writing simply fades from them if the player attempts to do so (preserving scrolls unlike the magic marker).
It is best used for engraving, as it produces graffiti (which is semi-permanent).
