Under the sweeping branches and leaves of the Highbranch tree and the apprentice's den, a long, thick log rests on the grass lengthwise. The log was hallowed and made into the elder's den. While being a den, it also acts as a good barrier, keeping cats from accidentally falling into the water on that side of the island. While elders complain that the den is too cramped, it's actually rather roomy, enough so that a few cats can stretch out comfortably inside or curl up without being too claustrophobic.
