The Iron Guardian of Frostkeep was an iron golem created by Lil, Marlissa and Mandis for the defense of Frostkeep against the gathered hordes of ice kobolds, gnolls and hobgoblins threatening Frostkeep. The Iron Golem proved to be an effective combatant, but after a battle in Frostkeep against the hordes of humanoids, Duke Deron Marlson lost control over the golem due to it being heavily damaged. The golem then wandered away on its own to the south, into the Shade Mountains.
