First leader of the Elvish Synfari; or wizard's council, and a key member of the royal court at Ectharë. Finarfen, as a powerdflu elvish mage owned a tall stone tower in side the elf-city of elutheria. It is said tha tthis tower had connections ot the underworld, although whether Finarfen created that connection, or the connection is why he built his tower there remains unclear.

For unknown reasons, Finarfen left his tower in Elutheria sometime in the Second Age, and traveled through the portal deep below deep below the surface. Once there he created a gigantic series of passageways and halls, known today as the Living Catacombs. Finarfen was an extremely powerful wizard, and some sages believe he left the elvish court and created his underground lair because his arcane powers drove him mad.

Finarfen is long gone, but the connection to the catacombs remains. In the present-day city of Atharavon, there is an inn called the Yawning Portal, which is built upon the entrance to the Catacombs.

His fate remains a mystery to this day.
