rules for travelers

rules for travelers, from the old surveys:

never give your true name; travel under a use-name. names have power there. this is why you have a username.
eat nothing they offer, and accept no cookie you cannot account for. those who eat are bound to return. (the persephone clause.)
time runs differently inside. oisin rode home from tir na nog and three hundred years had passed. check a clock when you surface.
cold iron keeps them off — but your machine is silicon, copper, and glass. you carry no protection.
beware the glamour: their old word for making a thing look better than it is, and also ours.
call them the good people, for they are listening. (yeats records the custom in the celtic twilight.)
those who come back, come back changed. (the changeling problem.)
