The card does not limit the target of it 1st effect to "an attack by Wolves, Spiders, Animals, or Undead against a ranger's company."Many Turns and Doublings wrote:Ranger only.

A ranger is a condition of the card, but not target, nor even an entity enacting 1st effect.
Therefore any ranger present in play may fulfill the conditions of the 1st effect of the card.
I propose the following erratum:
"Ranger only. Cancel an attack by Wolves, Spiders, Animals, or Undead against a ranger's company. Alternatively, if Gates of Morning is in play, decrease the hazard limit against the ranger's company by one (no minimum). He was taking a wandering course with many turns and doublings, to put off any pursuit.-LotRI"
