From Compendium of Worldly Lore
The celestial paragon embodies the divine power of good and righteousness. She channels the holy power of the Upper Planes in her battles against the forces of evil. Eventually, a celestial paragon transcends her normal form and becomes a celestial being.
Most celestial paragons are paladins or good clerics, though an occasional druid or ranger aligned with the forces of good follows the path. Multiclass fighter/clerics or monk/clerics make excellent celestial paragons. Other classes either lack the divine connection to the holy powers or aren't interested in such pursuits.
Celestial paragons are champions of good. At lower levels, they may work with other similarly minded individuals, but by higher levels they often serve at the right hand of their deities.

Class Features
All of the following are class features of the Celestial Paragon.
Weapon and Armor Proficiency: A Celestial Paragon is proficient with whatever they were already proficient with prior to taking levels in this class.
Spells per Day/Spells Known: At every odd-numbered level, the celestial paragon gains new spells per day as if she had also gained a level in a divine spellcasting class to which she belonged before adding the prestige class level. If already an epic spellcaster, the character gains only the benefit noted under the Spells entry for that epic class. She does not, however, gain any other benefit a character of that class would have gained (such as improved turning or lay on hands ability). If the character had more than one divine spellcasting class before becoming a celestial paragon, the player must decide to which class to add the new level for the purpose of determining spells per day (though she must choose a class in which she can cast at least 5th-level divine spells).
Planar Diplomacy Ex: The celestial paragon may add her class level to any Diplomacy checks made to adjust the attitude of an intelligent creature native to the Upper Planes.
Radiant Aura Su: A celestial paragon radiates bright light (equivalent in effect to the daylight spell cast by a character whose level equals the celestial paragon's divine caster level) at all times. The radius of this radiant aura is equal to 10 feet per class level. The celestial paragon can douse or relight this aura as a standard action.
Aura of Menace Su: Beginning at 2nd level, a righteous aura surrounds a celestial paragon when she fights or gets angry. Any hostile creature within a 20-foot radius of her must succeed at a Will save (DC 20 + celestial paragon level + Cha modifier) or be shaken for one day or until it successfully hits the celestial paragon that generated the aura. A creature that has resisted or broken the effect cannot be affected again by that celestial paragon's aura for one day.
Celestial Metamagic Su: Once per day, a celestial paragon of 3rd or higher level can treat any good spell she casts as if it were maximized. This has no effect on the spell's spell level or casting time. She can use this ability one additional time per day for every three levels gained above 3rd.
Holy Strike Su: Beginning at 4th level, the celestial paragon deals +1d6 points of damage whenever she strikes an evil creature with a melee attack. This bonus damage increases by an additional +1d6 for every four levels gained above 4th.
Healing Touch Su: A 5th level celestial paragon can heal injuries and other afflictions with her touch. Treat this as a Heal spell, except that it cures 100 + 10 per class level hit points of damage instead of restoring all hit point damage. The celestial paragon may use her healing touch one additional time per day for every five levels gained above 5th.
Timeless Body Ex: After achieving 7th level, the celestial paragon no longer suffers ability penalties for aging and cannot be magically aged. Any penalties she may have already suffered, however, remain in place. Bonuses still accrue, and the celestial paragon still dies of old age when her time is up.
Divine Transformation: At 10th level, the divine paragon becomes a native outsider. Her type changes to outsider, though she may still be raised or resurrected as normal. She also gains the good subtype. Thanks to this transformation, the celestial paragon gains SR equal to 31 + her class level.
