A valley within in the Dragon Knight's Domain, it is located on mountains so high that no human could ever reach the valley on foot; the only way to get there is via the Dragon Knight's transportation. The valley is home to a treasure trove of raw crystals, including some that are known to be "alive". It is also known for its unique flora, most notable of them being the Moonlight Weed, which was used as an ingredient to wake the Dragons from a sleeping spell late in the Toran Liberation War. A particularly nasty entity known as Crystal Core attacked Tir's group on their expedition here. Seek Valley is also the location of the hermitage of the Master Blacksmith Mace, who had chosen to live a more ascetic life, far away from civilization.
