It sounds like something is contained within this relic.
A Starved ancient effigy can be obtained as a rare drop from a large number of different monsters.
It can be turned into a Nourished ancient effigy by giving it one of two level 91 skills, yielding 15,000 experience in the skill used. Like the other stages, one skill of each pair can be assisted if the owner of the effigy does not have the required levels. However, using the assist system will cause the assister to get the experience instead.
