 Citadel of Celestis
The Citadel of Celestis, otherwise known as the Citadel of Mounting Heavens or simply 'Celestis' is the plane of the Lawful Good Alignment. It is a grand fortress based upon a great mountain with six layers, and upon the pinnacle lies the palace of Vasilios, the lord of the good gods, king of the Angels and second husband of Ashar. It is home to numerous celestial creatures including the Angels and Archons, who are the Petitioners of this Plane. Celestis is lit in eternal starlight.

 Features of the Plane
Mercuris, the First Layer: A shining sea of Holy Water, Mercuris is the First Layer of Celestia and is guarded by the White Ships, which take the souls of those faithful to the Triad to the Second Layer.
Exaltionis, the City of Faith: Exaltionis is the Second Layer of Celestis and is a city where petitioners wait in between their assignments. It is a beautiful place, the buildings are perfectly formed and everywhere is beautiful. Beyond the inner gates of the city lie the pathways that lead to Verdantis, the Third Heaven.
Verdantis, the Green Garden: This is a wild landscape of green fields and beautiful forests, where the halfling gods dwell. Ashar visits this layer sometimes, bestowing her care on the plants and making them grow healthier and greener than any plants on the Prime. At the end of this layer lie the Gates of Celestis, which no attacker has breached.
Celestis, The Invincible Fortress: This layer is a grand fortress, unsurpassed among mortal or immortal forts. Sofia dwells in this layer, atop the Tower of Guard, challenging all would-be attackers and evildoers to face her might. Of the few, terrible armies that have reached this layer, none have ever breached the walls. Moradin dwells there, as do the other gods of the dwarves. A thin and narrow path aids ascent to the layer of Martyris.
Martyris, The Plateau of Peace: The plateau here is seemingly barren, but actually far from it. This realm is a domain of ultimate peace, and all wounds inflicted here heal in instants. Poisons also heal, and Zenos walks this layer, giving peace and healing to all who require it. The way to the penultimate layer, Crystallis, is easy to find, if one is willing to look.
Crystallis, the Chilling Frost: Snow begins to fall now, and thick drifts cover the ground. The hoard of Bahamut flies above, surrounded by great flights of metallic dragons, and great spires of ice pierce the sky. The only way up now is via climbing - no aid now comes except from yourself.
Vasilis, The Summit of Good: The palace of Vasilios appears here, surrounded by clouds of Angels. Here dwells Vasilios, the unthreatened lord of all Good deities, and the chief God of Westhome.

 Plane Encounters
Warband: A small group of Celestial or Archon warriors, marching toward the front lines of some interplanar conflict. They are filled with conviction and wouldn't like distractions from their 'holy mission'. Best to avoid them, really.
Mortal Pilgrims: A group of pilgrims, trying to reach the top of Celestis. They are in good spirits, and are escorting something valuable (may be a holy relic, a dying friend, etc.) to the top of the mountain, and would not like it if this is threatened.
Lawbringers: A small celestial security team, dedicated to protecting Celestis from infiltrators. Made up of Sword and Lantern Archons led by an Angel. They are suspicious of strangers.
Fiendish Infiltrator: A fiendish infiltrator that is hoping to undermine the defenses of Celestis. They will attack any humanoid they see as compromising their mission on sight.
Berg: A moderate-sized village somewhere on the slopes of the mountain, reknowned across the planes for its hospital and inn.
Fiendish Portal: A Portal that leads directly to one of the Fiendish planes. This portal seems to grow slowly over time, and as time passes it might be large enough to unleash an army. The best thing to do is try and talk to the authorities, but are they to be trusted?
