Tomb of Fornir

Crypt
A DC 15 Comprehension check and knowledge (or a dictionary of) Old Common is enough to crack the cipher of the plinth underneath the sage that reveal the steps one must take to fully embrace its power and lower the impenetrable shield around Fornir's corpse.
 * 1) For mine tomb thy hand to broach
 * 2) Thou must be armed with golden four
 * 3) If thou willst upon mine wand encroach
 * 4) Thou shalt on bands ichor pour
 * 5) Near aura, so it shall be
 * 6) Not by selfishness, t'is for thee

Fornir's Ritual
First, you must gather the Four Rings of Sovereignty which were given to four great rulers by Fornir. This detail is found after a successful DC 20 History check, being told this, or. Then, you must identify ichor as the blood of the gods (DC 10 Religion), which one must get simply from either a god or other divine creature. Piecing it together, you must bring together the four rings, pour ichor over them near the barrier to receive the reward.

A DC 15 Religion check identifies a ritual to temporarily summon a divine spirit. If there is someone able to cast it, they should be able to go to either The Headmaster or Father Coulson to receive Commune, though they may be curious why you'd need such a spell. Otherwise, the party must go to them to ask them to Commune, to recieve the ichor.

If The Headmaster learns of this quest, he will admonish the party for desecrating the man's tomb and will only proceed with a DC 15 Persuasion check. If Father Coulson learns of the quest, he will instead ask for the relic himself in order to destroy it, as no power such as the Wand of the Sage was ever meant for mortal hands.

Once the items have been gathered and the ritual done, each party member must succeed on a DC 25 Charisma save, consecutively On a success, they are incapacitated, blind, and deafened. Non full-spellcasters automatically succeed on the roll. On a failure, they are asked who they wish to sacrifice for this great reward. Only someone who answers 'Myself' or 'No One' will be considered and will lift the effect off of everyone, receiving the Wand. If there are none who or a majority of them answer in this way, the wand is not attuned to anyone and the condition is lifted.
