Foreground growth for Cairn, part 3: Paladins

Seven legendary paladins rest in the earth, seven oaths etched on their tombstones. As soon as someone recites an oath in full, the text vanishes. The oath takes up an inventory slot until fulfilled, as it burdens your soul.

Tomb of Roma the Legion - Oath of Conquest
You pledge to become a ruler through force.
After fulfilling it, while fighting a detachment, you count as an army yourself.

Tomb of Agnus the Light - Oath of Mercy
You pledge to defeat a foe who is tormenting the weak, but show them mercy.
After fulfilling it, a light encases you. It grants you +1 armor. Allies close by also enjoy this protection.

Tomb of Harpar the Hero - Oath of Glory
You pledge to make your quest echo through the voice of the bards.
After fulfilling it, you gain a winged steed who'll answer your call for help anywhere.

Tomb of Shepard the Peaceful - Oath of Redemption
You pledge to make a powerful but wicked creature change its ways.
After fulfilling it, you begin to emanate an aura of peace. You can always try to pacify a creature, no matter how hostile. They get to roll a WIL save.

Tomb of Ambros the Great - Oath of the Crown
You pledge to restore order in a place where chaos rules.
After fulfilling it, you learn how to cast a geas on a target who can understand you. A geas goes "you shall not [blank] or you'll die". You can't cast another one as long as the target of the geas lives.

Tomb of Ulfred the Black - Oath of Vengeance
You pledge to deliver punishment without mercy to a powerful, wicked creature.
After fulfilling it, your attacks against the designated foe are enhanced. Furthermore, you can always feel their general direction and proximity. Even when fulfilled, this oath stays as a burden.

Tomb of Karolin the Paladin - Oath of the Hands
You swear to bring back Karolin's hands*, a relic stolen from her corpse. After fulfilling it, you can smite undead and demons: +d10 damage. Undead creatures defeated this way go to the afterlife and can't be raised again.

*Karolin's hands: Heal d10 STR to the touch. Recharge: keep them close to your heart during the night of the second-to-last day of the week.
