Timeless Monumental

Wandering between worlds, a massive fortress known as the Eternal Citadel collects forlorn travelers, hermits, and sole survivors to work in its service. Trapping these lost souls within its walls until they agree to follow the strange instincts brought on by the emotions and feelings the Citadel silently sends, this mysterious bastion works to preserve and protect all things, destroying only that which would bring ruin and desolation to the world. You are one of the few who have wandered inside at some point in your life, seeking shelter or knowledge, and now the influence of this place becomes clearly felt, granting you power and longevity to fight the forces of destruction for all eternity

Statuesque Physique

At 3rd level, your body begins to gradually become more refined, made perfect and whole in preparation for your work. Any physical deformities that you may have are fixed and your body is made whole again. Lost limbs reform, blemishes vanish, and your visage becomes timeless and clean. You gain advantage on Charisma (Persuasion) and Charisma (Performance) checks. If you take no damage for seven consecutive days, this process of purification and renewal occurs again at sunset

Gaze of Eternity

Also at 3rd level, your defensive prowess allows you to halt the progress of your foes. Hostile creatures cannot move through your space. If a hostile creature is within 10 feet of you, the weight of countless ages bears down upon them. If they attempt to move to another space that is further than 10 feet from you, they must first make a Wisdom saving throw with a DC equal to 8 + your proficiency bonus + your Charisma modifier. If they fail, they lose the ability to move farther away from you for the remainder of their turn unless they inflict damage upon you after failing their saving throw

Witness to Ruin

At 7th level, your transformation continues as you become further attuned to the Citadel. You no longer need to eat, drink, breathe, or sleep. In order to gain the benefits of a short or long rest, you must still spend the downtime performing only light activity. Your eyes see the small cracks and wear upon everything around you, allowing you to mark the passage of time with perfect accuracy. You can unerringly identify the true age of any person or object that you can clearly see, and you can choose to know the time that the person will die of old age based on their current health, diet, and lifespan, down to the day

Radiance of the Spire

At 10th level, your body and soul are bathed in the glorious light of the Citadel, granting you immortality. You no longer age and cannot be magically aged. Whenever you are reduced to 0 hit points, you are automatically stabilized. Once this occurs, you can’t gain this benefit again until you finish a short or long rest.

Titan's Virtue

At 15th level, you learn to call upon the triumphant power of the lost ages to contain the ruinous corruption wrought by mortality. Whenever you hit a creature that is within 10 feet of you with a weapon attack, it can’t choose to move to a location farther than 10 feet away from you during its next turn. If you move to a location farther than 10 feet away from it, then this restriction is lifted

Price of Preservation

At 18th level, you truly comprehend the nature of the Eternal Citadel, causing otherworldly power pour through you. When an ally within 15 feet of you takes damage from an attack, you can use your reaction to intercede on their behalf, teleporting in a flash of light to an unoccupied space within 5 feet of their attacker. The attack hits you instead, regardless if the attack would have missed you had you been the initial target. Immediately after the attack resolves, the ally can use their reaction to make a weapon attack against their original attacker.
