Coldarra Coldarra is an island just off the coast of the Borean Tundra in Northrend , and is home to the Dragon Aspect of Magic — Malygos . He is known to gather relics of great power , keeping them locked away from mortals in his lair , the Nexus . Frozen orc s , naga , troll s , and wendigo s that had dared to enter the sanctity of Malygos ' lair can be found throughout the island . They remain frozen , like statues , as a warning to those who would venture into the dragon ' s lair . The only access point is the bridge ( Frostbridge ) across the Westrift , requiring permission of the blue dragons guarding it to gain access . No one sets foot on Coldarra unannounced or uninvited . The entire island is made of ice , great jagged peaks that rise from the cold ocean like pale blue fangs . Some of those peaks rise high enough that one can see all the way to Crystalsong Forest and even to the Dragonblight . Dragons are the only inhabitants , not counting the occasional sheep or mountain goat . Rumors say that visitors sometimes stay to study with Malygos or record his tales , but no one settles permanently . The dragons don ’ t allow it . Because of this Coldarra has no Scourge presence . Coldarra is a large island — at least relative to the Northrend mainland . It is roughly a third as long as the mainland , though only as wide as the tip of the Borean Tundra or the Howling Fjord . Coldarra has no beaches and no gentle shore — its edges rear up as cliffs from the surrounding water . Most of the island is rock covered by thick ice , though here and there enough dirt has gathered to produce tough grass or small bushes . The dragons themselves live in caves fashioned from the cliffs and mountains , or in handsome stone buildings carved into the peaks . The island has no roads or bridges , save the one linking it to the mainland . The dragons fly everywhere , and carry guests from place to place . Coldarra is an irresistible lure for arcanists . Malygos is unquestionably the most powerful arcane spellcaster in all Azeroth , and designed not only most spells but the theories behind them . His libraries could make any mage powerful beyond his or her dreams , and even a few words with the ancient blue dragon could grant power and wisdom most mortals never achieve . Coldarra has only one real settlement . Blue dragons are solitary creatures . They prefer to live alone and meet only for discussion , flight or mating . One exception to the dragons ’ solitary existence is the Nexus , Malygos ’ s home and the dragons ’ center of knowledge . History . The blue dragons say Malygos , the oldest and greatest of their kind , created the spells that set the sky and the earth into motion . Harnessing the world ’ s magic and developing these spells took millennia ; he settled in the ice cliffs of Coldarra during that time . Other blue dragons joined him , though many lived elsewhere in the north . Then the black dragon Deathwing attacked the blue dragons , slaughtering them by the dozens . The survivors fought back but were no match for Deathwing ’ s ferocity . In the process their homes were destroyed and the land so damaged it could never recover . That area became the Dragonblight . Malygos , in his rage and grief , split his home from the rest of the land , creating the gap later named the Westrift . The remainder of the blue dragon race settled on Malygos ’ s island , which they named Coldarra , and carved out homes of their own . They gave up the war against Deathwing and the black dragonflight and chose to withdraw from the world . Soon they lost themselves in study , though always they look toward the Dragonblight and the spirits of their kin still lingering there . A cure for the Scourge ? An ancient scroll , found in a Northrend ruin , mentioned a spell that can remove undeath from a huge number of creatures at the same time , laying the undead creatures permanently to rest . Such a spell could rid the world of the Scourge for good and strip the Lich King of his power . The scroll had no details , but if such a spell does exist the blue dragons of Coldarra must know it , and possibly have it . All that remains is for heroes to gain access to the island and ask them — or , barring that , sneak onto the island unnoticed , sneak into the Nexus , and search for the spell without getting caught . Its unknown if anyone tried . Wrath of the Lich King . While it is separate region in the RPG , in the " World of Warcraft " expansion , Wrath of the Lich King , Coldarra shares the same map as the Borean Tundra rather than being on its own separate map . Coldarra is still marked on the map with the larger font used to designate separate regions . However , Coldarra is not marked on the main Northrend overworld map . Getting To Coldarra . Coldarra is only accessible via flying mount or via the flight point from Amber Ledge to Beryl Point . This flight point becomes accessible only after completing or . Speculation . Coldarra is a portmanteau of " cold " and " caldera " suggesting that long ago , before the Great Sundering and Northrend formed into an arctic tundra , it was the site of a large volcanic crater . Or perhaps it was simply a volcano that erupted during the Sundering and formed into a caldera . It is unclear whether the volcano itself is dormant , but given extreme damage sustained by the Sundering , the molten cavity could have collapse there by rendering Coldarra completely lifeless .
