Mor Dhona Mor Dhona is a region in " Final Fantasy XIV " in the world of Hydaelyn , on the realm of Eorzea , and on the sub - continent of Aldenard , to the southeast of Coerthas and north of Thanalan . The whole area had been rendered barren and corrupt of aether during a massive battle between an army of dragons led by the Wyrmking Midgardsormr and a fleet of Garlean airships that happened fifteen years ago , shown during the game ' s original opening CG . The battle turned the place into a dangerous , lifeless place full of terrible beasts , and became later known as the Battle of Silvertear Skies . It would be further transformed by the fall of Dalamud at the end of the Sixth Astral Era over a decade later . Profile . Mor Dhona long laid between the various city - states of Eorzea , and generally unclaimed by any . It was said that since immemorial times , a great force slumbered there . This force was said to drain the element from anything that remained in contact with the ground for a long time ; if a wind crystal was buried there , for example , it soon became a pure crystal devoid of wind properties . In spite of this , Mor Dhona was famous for its wild and rugged beauty , particularly its lush green forests and striking waterfalls , which fed into and out of one of Aldenard ' s largest inland bodies of water : Silvertear Lake . It was the unclaimed nature of the area , as well as its central position on Aldenard and its verdancy , that likely attracted the attention of the Garlean Empire . After taking Ala Mhigo , the Imperial Air Fleet made a move en - masse into Mor Dhona , led by the mighty super - dreadnought , the " Agrius " . However , as the imperial fleet advanced into the skies above Silvertear Lake , it was met with a wholly unexpected sight . Midgardsormr , the dragon deity of Silvertear , had arisen , summoned by a hand unknown . And as if to answer the mighty wyrm ' s call , a host of dragons flew in from the northwestern reaches of Dravania and fell upon the Empire ' s forces . The air was filled with the deafening roars of cannons and dragonkin alike . Locked in a deadly embrace , the thunderous impact of Midgardsormr and the " Agrius " tolled their mutual demise . Thus ended the Battle of Silvertear Skies - and one of the greatest defeats Garlemald had yet experienced in their campaigns of conquest . Ceruleum leaking from the fallen airship , combined with Aether from the dying dragon king , would soon transform the flora of Mor Dhona into crystallized structures that remain visible to this day . Many years later , the Battle of Carteneau ended with half of the region devastated by the effects of Bahamut emerging from Dalamud . Today , Mor Dhona stands as perhaps the single most scarred , battle - blasted region in all of Eorzea ; having been the stage for " two " of the most destructive battles in recent Eorzean history , and the first focus of Bahamut ' s awakened rage , much of the region is now desperately barren , crystal - scarred and uninhabitable , a far cry from its old verdancy . Even now , the carcass of Midgardsormr lies entwined with the wreckage of the " Agrius " in the center of Silvertear Lake , a towering monument to the ferocity of the conflicts that have ravaged this land . Locations . Mor Dhona lies at the center of Eorzea . A path out of Revenant ' s Toll leads to the Coerthas Central Highlands , while a bridge leading out of Castrum Centri leads to Northern Thanalan . Aetherytes . The only Aetheryte is located at Revenant ' s Toll . Areas . Mor Dhona contains the following areas : Settlements . Revenant ' s Toll . The original Camp Revenant ' s Toll was annihilated in the Calamity , and the crystal grew out of the ground to engulf the otherwise pristine and uniform Aetheryte crystal . Players can still navigate the ruined camp in various quests , but all NPCs have either died or moved to the new , full - blown " town " of Revenant ' s Toll , situated nearby . It has been growing larger as time passes in the game . Saint Coinach ' s Find . The Sons of Saint Coinach , an organization of scholars and researchers from Sharlayan , have made camp in these Allagan Ruins . In addition to the ruins , the suddenly formed Crystal Tower is a valued subject for study . Weather . Mor Dhona ' s environment may exhibit any of the following weather conditions : Places of Interest . Crystal Tower . The Crystal Tower sprang up some time shortly after the Calamity . The Sons of Saint Coinach would likely unlock its odd , slanted door were it not for the hostile Gigas roaming the area that appear to worship the tower . Along with the Keeper of Lake , the tower dominates Mor Dhona ' s modern landscape . The Keeper of the Lake . Located in the middle of Lake Silvertear lies the ruined hulk of the " Agrius " , with the wyrmking ' s carcass entwined around it . Along with the Crystal Tower , it remains the definitive landmark of the region . Singing Shards . A huge cluster of crystal formations to the north of Saint Coinach ' s Find , with a crater lake in the middle . A fragment of Dalamud had landed here during the Calamity , which still crackles with energy . The Tangle . One of the most intriguing spots for its reason for development , the Tangle is a labyrinthine forest full of Morbols just outside Castrum Centri . It was made to resemble the spot the CG Midlander fought the Malboro during an Echo in the original game ' s Opening Movie . Needless to say , the swamp is also quite perilous . Castrum Centri . Castrum Centri was once Castrum Novum , remodeled and renamed after the XIVth Legion took over from the tattered remnants of the VIIth . It serves as one of the cores of the Garlean Empire ' s presence in Eorzea , along with the Praetorium . Rathefrost . Situated on a cliff to the west of the " Agrius " , a large tree stands crystallized since the fallout of the Battle of Silvertear Skies . A stone bearing the mark of Thaliak the Scholar lies in front of it . More unusually , several Harriers from Coerthas have been seen in the path leading to the crystal tree . Carteneau Flats . After the fall of the White Raven , the remnants of the VIIth Legion had moved to these barren fields . The Eorzean Alliance engaged the VIIth Legion during the Battle of Carteneau in order to ensure Louisoix could summon The Twelve in a desperate attempt to halt Dalamud ' s descent . During that fateful battle , the falling moon disintegrated and released the Elder Primal Bahamut who forever changed Eorzea ' s landscape in its fury . Since then , the Carteneau Flats have been discovered to contain many buried ruins of ancient Allag . Conflict over this is regulated by the Frontline campaigns conducted by the Grand Companies of Eorzea . Yafaem . These saltmoors are located northwest of Lake Silvertear . Once the site of a great city of magic in the Fifth Astral Era , the Great Flood of the Sixth Umbral Era felled the black mages of Mhach and transformed Yafaem into saltmoors . Versions . Original ( 1 . 0 ) . The original Mor Dhona served as nothing more than a dangerous location for a meager few main scenario quests . Until the addition of Notorious Monster s like Dodore , the region saw very few visitors outside the occasional toad farmer . Full of empty caves and dummied content , explorers found it a great place to speculate what might have been in the original game ' s endgame . Late in the Seventh Umbral Era story , the Garlean Empire established a makeshift stronghold called Castrum Novum , their second foothold in Eorzea after Ala Mhigo . " Final Fantasy XIV : A Realm Reborn " . The most notable change is the absence of the entire southern half , likely obliterated or rendered uninhabitable after Bahamut ' s rampage at the Battle of Carteneau . The aether crystals have grown even further at places , particularly in the area of Singing Shards , where the entire canyon is crystallized to the point where electricity can be seen sparking from wall to wall . Gigas and hippogryphs have moved in from the mountains of Coerthas , and piestes have migrated to the adjacent Northern Thanalan . While much of the area is just as barren as it had been since the Battle of Silvertear Skies twenty years ago , plant life has returned in full force in spots like The Tangle . Quite unlike Version 1 . 0 , Mor Dhona and particularly Revenant ' s Toll are now the go - to hub for end - game coordination , due in large part to the presence of the " tome vendors " - merchants who will trade various endgame items and crafting materials for Allagan Tomestones . The Crystal Tower is also located in Mor Dhona , meaning the entrance to at least one end - game dungeon is right there as of patch 2 . 1 . Additionally , Revenant ' s Toll ' s popularity is so prominent that it is acknowledged in the story itself - the camp - cum - city is growing with the players , and the Scions of the Seventh Dawn even move their headquarters there to be closer and more convenient for the adventurers . This growth is also reflected with patches , as the town is getting incrementally built , with the town square complete as of Patch 2 . 28 , and with Rowena ' s " House of Splendors " complete as of 2 . 5 .
