In the zone "a decrepit crypt", entered via Turmoil Cemetary (click the tomb in the building), the end mob is Lucas Steelbone and his brother Palinus Steelbone the Third (and his necro pet). You can fight them separately. Level 12-14 heroic ^^^. Easy fight for a solo warden on-level as long as you heal yourself. Treasure is old school, not useful anymore.
